Supply Input and Power On Reset
The uP9509 receives supply input from PVCC pin to providecurrent to gate drivers and internal control circuit. PVCC iscontinuously monitored for power on reset. The POR levelis typical 4.1V at rising. The TON pin voltage is used foron-time calculation and should be connected to the supplyinput of power stage.
The uP9509 integrates floating MOSFET gate driver thatare powered from the PVCC pin. A bootstrap schottky diodeis embedded to facilitates PCB design and reduce the totalBOM cost. No external Schottky diode is required in realapplications. An external Schottky diode with lower voltagedrop can improve the power conversion efficiency.
Phase Number of Operation (Hard-wire Programming)
The uP9509 supports 3/2/1 phase operation. The maximumphase number of operation is determined by checking thePWM3 status when POR. Connect PWM3 pin to GND with100kΩ resistor for maximum 2-phase operation; ConnectISEN2 to PVCC with 100kΩ resistor for maximum 1-phaseoperation. Once selected, the maximum phase number ofoperation is latched and can only be changed at the nextPOR.
Constant On-Time Setting
The uP9509 adopts a compensated constant-on-timecontrol scheme. A resistor R
TON connected to TON pin
programs the constant on time according to the equation:

Functional DescriptionBoot Voltage and Standby Mode
The new generation PWMVID structure includes twooperation modes other than normal operation: boot modeand standby mode. During boot mode, the GPU stopssending PWMVID signal and the input of the PWMVID bufferis floating. The REFADJ pin enters high impedance stateafter the VID pin enters tri-state region, and the REFINvoltage can then be calculated as:

During standby mode, other than GPU stopping thePWMVID transaction, an external system standby signaladditionally controls the entry of standby mode. Anadditional external switch should be connected in parallelwith the original PWMVID resistors as shown in Figure 3to generate the standby mode voltage:

Current Sensing Scheme
The GM amplifier senses the voltage drop across the low-side MOSFET and converts it into current signal each timeit turns on. The sampled and held current is expressed as:
( )( )ISENX
DCONDSLXCSX R
VRII
+×=
where ILX
is the phase N current in Ampere, RDS(ON)
is theon-resistance of low-side MOSFET of the power stage inmΩ, V
DC is an internal 30mV voltage source, and R
ISENX is
the external sensing resistor connected at ISENx pins. Inthis current sense mechanism, the valley of the inductorcurrent is sampled and held. Therefore, the equivalentsensed current can be described by the following equation:
LXAVG_LXSH_LX I21
II ∆×−=
The sensed current ILX_SH
is mirrored to the current balancecircuit, comparing between each other, and generatingcurrent adjusting signals for each phase. These currentadjusting signals are fed to the on-time circuit of the uP9509to separately adjust each phase on-time for the purpose ofadjusting current balance.
Soft-Start and Power Good
A built-in soft-start is used to prevent surge current frompower supply input during turn on. The error amplifier is athree-input device. Reference voltage V
REFIN or the internal
soft-start voltage SS whichever is smaller dominates thebehavior of the non-inverting inputs of the error amplifier.SS internally ramps up to PVCC with a slew ratedetermined by V
REFIN after the soft start cycle is initiated.
Accordingly, the output voltage will follow the SS signaland ramp up smoothly to its target level. The output voltageramp-up time can be selected through a resistor which isconnected from LGATE2 to GND. The output ramp-upselection table shown as following table.

Power Saving Mode
The uP9509 provides power saving features for platformdesigners to program platform specific power savingconfiguration. There are four operation modes: multi-phaseCCM, multi-phase DCM, single-phase CCM, and single-phase DCM. The uP9509 switches between these fouroperation modes according to the input voltage level of thePSI pin. Figure 5 shows typical PSI application circuit,and table 1 shows recommended PSI setting voltage levelof four operation modes. In single-phase operation, theuP9509 auto-selects phase 1 to be the operating phase. InDCM, the uP9509 automatically reduces switchingfrequency at light load to maintain high efficiency. As theload current decreases, the rectifying MOSFET is turnedoff when zero inductor current is detected, and the converterruns in discontinuous conduction mode.

Over Current Limit
The uP9509 monitors the inductor valley current by lowside MOSFET R
DS(ON) when it turns on. The over current
limit is triggered once the sensing current level is higherthan V
OC. When triggered, the over current limit will keep
high side MOSFET off even the voltage loop commands itto turn on.
The output voltage will decrease if the load continuouslydemands more current than current limit level. The currentlimit threshold is set by connecting a resistor (Roc) fromLGATE1 to GND. The voltage across PHASE and GND pinsis compared with V
OC for current limit. The current limit

Over Voltage Protection (OVP)
The OVP is triggered if VFB
> 1.5xVREFIN
sustained 6us.When OVP is activated, the uP9509 turns on all low-sideMOSFET and turns off all high-side MOSFET. The overvoltage protection is a latch-off function and can only bereset by PVCC re-POR or EN restart.
Under Voltage Protection (UVP)
The under voltage protection is triggered if VFB
< 0.5xVREFIN
sustained 10us. When UVP is activated, the uP9509 turnsoff all high-side and low-side MOSFET. The under voltageprotection is a latch-off function and can only be reset byPVCC re-POR or EN restart.
Over Temperature Protection (OTP)
The uP9509 monitors the temperature of itself. If thetemperature exceeds typical 150oC, the uP9509 is forcedinto shutdown mode. The over temperature protection is alatch-off function and can only be reset by PVCC re-PORor EN restart.
