1 Overview
PM3533 is RF energy management and RF FE control device that contains following functionalities: SMPS (Switched Mode Power Supply), Boost DC-DC converter, Buck DC-DC converter, several regulators for internal use and one regulator for external use. PM3533 also contains two antenna control IOs and two PA bias DAC outputs with the possibility to use the second DAC output also as third GPIO.
Figure 5. PM3533 functional block diagram
1.1 Main features• Antenna controls and PA control signals
– Two antenna-tuning controls. Controls are programmable via the Serial Peripheral Interface (SPI).
– One adjustable current reference for PA, with two multiplexed outputs.
– One of the outputs can also be used a static control output
• SMPS converter
– SMPS converter optimized for both GSM and WCDMA power amplifiers
– GSM mode bursts ramp-up/ramp-down capability
– Two different operating modes, which are controlled via Serial Peripheral Interface (SPI). The operating modes are used to optimize SMPS efficiency at lower power levels. Operation modes are explained in Section 1.1.1.
– Internal adjustable switching clock
– Dithering. Dithering adds deviation to switching frequency, which lowers switching harmonic at output of SMPS. The deviation of the dithering is adjustable between two different frequencies.
– Adjustable delay control for SMPS power switch drivers.
– Adjustable integrated loop-filter.
• Boost DC-DC converter
– Boost DC-DC converter regulates the battery voltage up to 4.0 V, 4.3 V, 5.3 V or 6 V.

– Three different operating modes are controlled by the Serial Peripheral Interface (SPI). The operating modes are used to optimize the power converter efficiency at lower power levels. The operation modes are explained in Section 1.1.1.
– Sampled soft-start, to enable smooth transient behavior on Boost DC-DC converter output when starting the device or to continue from earlier idle (with its output already at the correct level)
– Internal adjustable switching clock.
– Dithering. Dithering adds deviation to switching frequency, which lowers switching harmonic at the output of the boost DC-DC converter. The deviation of the dithering is adjustable between two different frequencies
• Buck DC-DC converter
– The buck DC-DC converter down-regulates the battery voltage to 1.45 V.The output voltage is adjustable also to 1.65 V or 1.35 V, another normal usage set is 1.85 V or 1.55 V.
– Sampled soft-start, to enable smooth transient behavior on Buck DC-DC converter output when starting the device or to continue from earlier idle (with its output already at the correct level).
– Internal adjustable switching clock.
– Dithering. Dithering adds deviation to switching frequency, which lowers switching harmonic at the output of the buck DC-DC converter. The deviation of the dithering is adjustable between two different frequencies.
• External regulators
– PM3533 has one regulator for external use. VHI regulates the battery voltage to 2.6 V or 2.5 V. VHI is enabled automatically after power-up with default output voltage of 2.5V.
• Multiplexer
– PM3533 has one programmable multiplexer used to switch several analog node voltages to PM3533 MUX1 I/O. The battery-monitoring block is also connected to the multiplexer. Additionally MUX1 I/O can be used for self-testing purposes.Multiplexer structure is shown in Figure 22.
• Serial Peripheral Interface (SPI) for PM3533 control.
• Battery monitoring block. This block enables battery voltage monitoring during the operation and can also be used for self-testing purposes in production line.
• Under Voltage Lockout block. This block adds special protection by automatically powering-down the boost power converter if abnormal power-downs occur at full power mode.
• 40-bit OTP memory. One time programmable memory is needed to switch the frequency tuning for all three converters. Also TSD (Thermal shutdown cell) can be tuned with OTP memory.
• Thermal shutdown
– Thermal shutdown circuitry monitors the die temperature and fulfills a shutdown when a specified temperature is reached. Thermal protection is enabled automatically after power-up.

1.1.1 Special power saving modes
DCDC converters have “low power” operation modes, which reduce the current consumption in low power mode. The modes are controlled through the serial control interface.
SMPS converter
1. “Low power” mode means that the size of power switches including the drivers are reduced at lower power levels.
2. Power switches are divided into two parts. In high power levels both parts are used while in low power levels only 1/3 part of the switches and their drivers are used. The decision on which mode is used comes from the base-band.
Boost DC_DC converter
Boost DC_DC converter includes two different power saving modes.
1. “Full power” mode means that the boost DCDC converter at normal operational mode with the full output power capability. Enabling of this is coming from the base-band.
2. The boost converter has also a “By-Pass” mode, which corresponds to 100% duty cycle operation. In that mode the converter upper switch is turned on while the converter lower switch is turned off. The boost by-pass function can be used in low power levels by shutting down the boost-converter.

8.1.1 Power up for VHI regulator
VHI regulator’s power-up-timing-sequence is presented in Figure 15. The VXO supply voltage is used as enable signal for the VHI regulator. VHI regulator uses VREF as reference voltage and hence VREF must be activated for VHI to settle to the right output voltage level. The timing diagram below is representative only and therefore real power-up timings are linked to different application use cases and external filtering components (for instance on the external Vref line).

9 Digital to analog converter
There is one 6–bit D/A converter inside PM3533 designed for PA bias control. The converter is supplied from VHI –supply and it provides a maximum output current up to a 2.2 V output voltage level. The DAC output is multiplexed between two different outputs PADAC1 and PADAC2. The DAC value and multiplexing are controlled via SPI.
Figure 16. DA-converter block diagram
Note: Unused PADAC output should be left floating (it is internally pulled-down while at an off state).
Operation characteristics are presented in Table 21.

In addition to normal usage of the current mode PADAC it is possible to use extra added feature in order to use a coded output current to have a better accuracy of PADAC output current. During a mass-production phase and its OTP fusing phase PADAC output current by a certain code of 48 [in dec] is read/saved to certain register bits so this information can be taken into use by combining dedicated bits. Look at the register table in the end part of this datasheet for further details of registers available.
The application sw is able to read these dedicated bits in the following way:
After a normal power-up, read reg15.bit_numbers of [10,5,0] + reg2.bit[7] = MSB…LSB order of bits for saved value and by looking at the accurate measured output current value like it is coded in the table below.
INL1 Integral non-linearity 1.5 LSB
Monotonic behavior required @ VHI = 2.5 V
INL2 Integral non-linearity 0.9 LSB
Monotonic behavior required @ VHI = 2.6 V
DNL Differential non-linearity 0.5 LSB

The following kind of an accuracy can be achieved through setting of reg9.bits[15...9] i.e. ‘1100001’ which equals to 48 [in dec] + enable_bit_of_padac. This setting is used while the coded value is saved like informed for corresponding output current values in the table above, thus being saved during the fusing phase of the mass-production testing
Then it is straightforward to use this information like matching a linear equation with the following characteristic equation:
PADAC_output_current(Padac_output_code_wanted)
= (y_offset / (48 - 1)) * (Padac_output_code_wanted - 1) + min_LSB_size
In which
min_LSB_size = 33uA
y_offset = Coded_value - min_LSB_size
* Coded_value (in μA) is read from the table PADAC coding table
With this added feature the following kind of an accuracy of
PADAC_output_current (Padac_output_code_wanted)
can be achieved as a function of different PADAC control bits in Reg9[15...10]:

11 Thermal shutdown
The thermal shutdown block protects the PM3533 from over-heating. The TSD block is used to shutdown functions when the temperature threshold limit is reached. When the temperature level is reached TSD shuts down the power stages of all converters, however all other PM3533 blocks are still active.
The TSD function is enabled automatically whenever a power-up sequence is controlled. See the power-up diagrams for futher details in Figure 23.

12 OTP memory
One time programmable memory cell (OTP) is used for tuning purposes during PM3533 mass-production testing phase.
Basic functionality of OTP macro cell: data is programmed serially through SCANIN pin on each CLOCK rising edge. OTP is programmed using an external high voltage HV solder bump at a wafer level. To sense the data stored in cell, a RESET pulse is required after power on. Fuse_ok signal indicates that data is available on D0 to D39 pins. PROG pin is needed to select the 20-bit block for the programming.
PM3533 digital cell includes a multiplexer, which needs enabling and Fuse_ok controlling bits. Fuse_ok is generated during the OTP programming procedure, it indicates if the data_set is corrupted. If Fuse_ok is “1” and enable Reg14(15) bit is “0” the data set from antifuse can be used. If Reg14(15) is high and Fuse_ok is low, the multiplexer outputs the data which is programmed in register REG14(15:0). Reg15(15:0), Reg13(3:0) and Reg12(15:0) can be used to read the whole OTP(39:0) memory content of two 20-bit memory blocks, these are available through the SPI (Serial Peripheral Interface) access to read all the OTP memory bits.

14 Under-voltage-lockout block
PM3533 includes an Under Voltage Lockout block. This block provides special protection mode to PM3533 and especially to its boost power converter while it is working at full-power mode and the modes of operation include sudden or abnormal power-downs (i.e. uncontrolled states of critical supply voltages like those are disappearing suddenly especially VBAT and/or VXO before XRESET signal is set low by an external control see Figure 24.)
When UVL triggers it disables the internal control signals of the boost converter block which further disables the power stages of this converter making it disabled. This way boost converter is inhibited to have unwanted overshoots at its output voltage during like out-of-spec (VBAT/VXO uncontrolled power-downs) situations.
This function is automatically enabled when normal power-up is controlled, as shown in Figure 23. The function is kept enabled by hard-wired internal control signals. Only the Xreset signal asserting to '0' disables this function (at the reset state of PM3533).

16 Modes of operation
The device has several operating modes. There are a few active modes, power–down mode and several test modes. Most of the blocks can be turned on and off individually through the serial interface. The operating modes are described in the following sections.
16.1 Power UP/DOWN sequencePower UP/DOWN sequence described here must always be followed when powering the IC UP or DOWN (an order of external supply voltages and control signals). Mis-use of the IC can lead to shorter lifetime. The timing diagram below is representative only and therefore real power-up timings are linked to different application use cases and external filtering components (for instance on the external Vref line).
Note: Internal VDIG_int which gives a supply voltage to the digital interface of PM3533 follows approximately a rise time of the Vref line after high state of which (five worst case time constants of RextCext) PM3533 is ready to receive more accesses for controls i.e. external component filtering on the vref line dominates the wake-up time of PM3533 added with max current capability of an external buffer driving this external Vref line during its rising period. After all this Xreset is released and control accesses are allowed.

17 Control interface
17.1 Data interfacePM3533 is programmed via the serial bus (SLE,SDATA,SCLK and RESET). SDATA data is clocked by SCLK rising edge. The data is fed with MSB first and address bits before data bits. PM3533 is in RESET state, when RESET signal is logical low.
Figure 25. Timing waveform of writes cycle
Note: On SCLK rising edge, one bit of data is shifted in the shift register. SLE should be kept high when the interface is not used
Figure 26. Timing waveform of read cycle
Note: Data should read at the falling edge of SCLK.

20 Example of WCDMA output power distribution curve
The most important driver for PM3533 is to increase efficiencies in WCDMA low power levels. Figure 29 presents the DG09 WCDMA output power distribution curve. The power distribution curve shows that in WCDMA system the mobile transmitter is almost all of the time in power level area comprised between 6 dB and -12 dB.

Ref. Min. Typ. Max. Unit
A(1)
1. VFBGA stands for Very thin profile Fine pitch Ball Grid Array.- Very thin profile:.
- The total profile height (Dim A) is measured from the seating plane to the top of the component.- The maximum total package height is calculated by the following methodology:
1.00 mm
A1 0.125 mm
A2 0.19 mm
A4 0.585 mm
b(2)
2. The typical ball diameter before mounting is 0.25 mm.

eee(3)
3. The tolerance of position that controls the location of the pattern of balls with respect to datums A and B. For each ball there is a cylindrical tolerance zone eee perpendicular to datum C and located on true position with respect to datums A and B as defined by e. The axis perpendicular to datum C of each ball must lie within this tolerance zone.
0.15 mm
fff(4)
4. The tolerance of position that controls the location of the balls within the matrix with respect to each other. For each ball there is a cylindrical tolerance zone fff perpendicular to datum C and located on true position as defined by e. The axis perpendicular to datum C of each ball must lie within this tolerance zone. Each tolerance zone fff in the array is contained entirely in the respective zone eee above The axis of each ball must lie simultaneously in both tolerance zones.
