1). Power Board Operation Therory

1.1 Line filter consists of C801, T801, C802, C803, C804, C809, C815, C838, R801. It eliminates high frequency interferenceto meet EMIs requirement.

1.2 Rec & FilterBridge diode D801 converts AC source into pulsed DC. This pulsed DC is smoothed and filtered by C805. R802 isan NTC ( negative thermal coefficient ) resistor, used to reduce inrush current to be within safe range.

1.3 Power transformer :T802 converts energy for square wave from power source C805 to secondary side to generate +5V, +12V and+21.5V.

1.4 Output :The square wave from T802 is rectified by D808 D809, D810, then filtered by C818, C824, C829, C813 ,C822 togenerate +21.5V and +12V, +5V respectively.

1.5 Driver :Q803 drive T802 from PWM control of I801 for power converted.

1.6 FB :Negative feedback CKT consists of photo coupler I802 and adjustable regulator I803. It can maintain outputvoltages +21.5V and +12V, +5V at a stable level.

1.7 PWM :1.7.1 Start : When power is turned on. C807 is charged a 12 volt and a starting current above 1mA to pin 1 of I801.

I801 starts to oscillate and outputs a pulse train through pin 6 to drive Q803.1.7.2 OPP : When Q803 turns on, C805 supplies a linearly increasing triangle current through the primary induc-

tance of T802 to the driver Q803, once the peak value of this current multiplied by R811 exceeds1 volt, pulsetrain will be turn off immediately to protect Q803, T802 from being burned out.

1.7.3 Regulation : If output voltage +21.5V goes up, the R terminal of I803 gets more bias, accordingly phototransistor and photo diode flows more current. The voltage of pin 2 goes up too, making the pulse width ofpin 6 to become narrower. So the output voltage +21.5V will be pulled down to a stable value.

1.7.4 OVP : If +21.5V goes up too much, the induced voltage on pin 4 of T802 becomes large also. Suppose that itis over 18 volts. The pulse train at pin 6 goes down to zero, shutting Q803 off immediately.

1.7.5 SCP : If output terminal is short to ground, photo transistor does not conduct, hence Q807 does not conduct

either. Then oscillation of I801 is stop, shutting Q803 off immediately.

2) Inverter CircuitThis unit operates on an output voltage of 21.5V from power source.

2.1 VDD: R105 get a +5VDC for I101 power supply.2.2 Control IC: I101 (OZ9930)2.2.1 Enable : When pin 1 of I101 is over 0.55V, I101 works. If it is under 0.55V, I101 turns off.2.2.2 OSC: When I101 enabled, C104/C105 (pin 2 of I101) determine the operating frequency.2.2.3 SST: C106 (pin 1 of I101) provides soft start function.2.2.4 Ignition: IC provides higher operating frequency internally for more striking voltage until regulation of feedback of

lamp current. And provide 2 sec striking time.2.2.5 Dimming control: The divided voltage of R106/R103/R104 control the duty pulse of burst-mode to drive and

perform a wide dimming control for the CCFL. The burst-mode frequency is determined by operating freq/233.2.2.6 Regulation: Pin 8 of I101 provide regulation of the CCFL current from feedback. The non-inverting reference is at

1.25V nominal.2.2.7 Protection: Open-lamp protection in the ignition period is provided through pin 7 of I101.

Removal of the CCFL during normal operation will trigger IC to turns on and shuts off the inverter. This is latchfunction.

2.2.8 Output drivers: The configuration prevents any shoot-through issue associated with bridge-type powerconversion applications. Adjusting the overlap conduction between Q104, the CCFL current regulation is achieved.

2.3 Half-bridge swit ching/Transformer: Q104, C122, C123 compose half-bridge swit ching to convert DC into AC fordriver the CCFL.

2.4 Detection: C132, C112, C114, C126, R116, R115, C115 detect the output voltage and ensure a rated voltage by pin7of I101 ensure not a open-lamp.

2.5 Feedback: D116, D117, R111, R112, C109 sense the lamp current for negative feedback and regulation.

The I307 gm2621 identifies the ON status of the two power supplies. The identification ismade when the power supply is turn off. For example, if the power supply is turn off withthe POWER switch, the POWER switch must be turn on when active the power supplyagain. If the power supply is turned off by pulling out the power cord, then this powersupply can be turned on by connecting the power cord, without pressing the POWERswitch.

3.7.2 Display mode identification3.7.2.1Display mode identification The display mode of input signal is identified based on Table 2.

When the mode has been identified through the measurement of horizontal andvertical frequencies, the total number of lines is determined with a formula of Hori-zontal frequency / Vertical frequency = Total number of number of lines. Finalidentification can be made by examining the coincidence of the obtained figure withthe number of lines for the mode identified from the frequency. The DistinctionHsync and Vsync of each mode is shown in Table 3.

When the detected frequency if the sync signal has changed, the total number oflines should be counted even through it is range identified frequency in the samemode.

3.7.2.2Out of rangeThis out of range mode is assumed when the frequency out of the horizontal /vertical signal is as specified below.

Vertical frequency : 56 ~ 76 Hz. Horizontal frequency : 30 ~ 63KHz.3.7.2.3Power save mode

The power save mode is assumed when the horizontal / vertical signals are asspecified below.

If there is no horizontal sync signal input. If there is no vertical sync signal input.

If the horizontal sync signal is outside the measuring range of I307 gm2621. If the vertical sync signal is outside the measuring range of I307 gm2621.
