DC_5V through C23 and C2 will provide power for U1 on the pin6.
EN-ON/OFF voltage signal coming from scalar which is on IF BD will enable U1 to work.
During start up, The voltage of SST_CMP is determined by Pin8(ISEN).When ON/OFF signal is off,
MOSFET Q1 will be closed, then upper resister R22 give high signal to Q2’ GATE pin, and make
IC’Pin1(SST_CMP) to GND, so IC will shut down. If giving a high signal to Q1, Q2 will be
closed .then Pin1 will be floating. Once the voltage at the ISEN pin reaches the lamp on threshold,
the IC switches from the striking mode to the normal operation mode and the PWM dimming
control is activated. At the same time, the voltage of Pin1 will change following the voltage of Pin 8.
R5 is limited current resister and C6 accomplishes the soft start function.
DIM-ADJ duty cycle signal through R3 and C5 is on Pin 7(DIM), which will adjust IC’ output
duty cycle, then changing the brightness of Panel
The striking and operating frequency is determined by the external resistor (R4) connected to Pin
2. The striking frequency is 1.3 times of normal frequency.
DRV1 and DRV2 of U1 are used to drive Q4. DRV1 and DRV2 are controlled by build-in PWM
IC. DRV1 is reverse with DRV2.Q4 is built in 2 N-chanel MOSFET. DRV1 and DRV2’PWM signal

drive Q4, this push and pull the energy in the transformer.
The voltage signal on negative pole of ZD4 sensed through R35 comes to Pin4 of U1, ISEN
(Lamp Current Detection & Control). The CCFL current is detected through R14and reaches a
regulated value. The CCFL current detected at resistor R14 is converted to a voltage level and
input to the ISEN pin.C12 is used to dump noise. Once the CCFL are ignited and current is sensed
through resistor R14 .capacitor C12 performs the loop compensation function. The voltage at IC
pin8 controls the drive duty cycle of the power MOSFET to regulate the CCFL current.

C9 and C2 is the filter capacitance.R17 and C21 as the snubber circuit will decrease the peak
voltage on Q4 drain pole witch have bad effort for MOSFET safety area.R18 and C22 have the
same effect with R17 and C21.C8 and C27 will deeply decrease the voltage on Q4 drain pole.
The transformer (T1) secondary winding leakage inductance and output capacitance(C18)
forms a lower pass filter, which converts the square-wave driving signal into a sinusoidal output
voltage signal for CCFL.
The over-voltage protection feature is implemented by using an external capacitor
devider(C13/C14,C17/C19) to sense the output voltage.The divide-down voltage signal is
transferred though ZD5 and ZD6,witch will rise the OVP voltage ,then this OVP signal though Q3
determine the voltage of SST_CMP ,thus regulating the output voltage.
If a CCFL is removed, fails or damaged during normal operation, CCFL current is no longer
sensed and the voltage on ISEN pin drops. Once the voltage at the ISEN pin is less than the lamp”
on” threshold, the shutdown timer is activated. The IC maintains the output voltage for
approximately 2-3seconds and once the timer expires, the IC will shutdown. To restart the IC, either
toggle the SST_CMP pin or recycle the power on the VDDA pin.

D850 is a rectifier in which there are 4 build-in diodes, inverting AC to DC.
C854 is used to smooth the wave from rectifier. R839 is a fuse resistor to protect the following
circuit when inrush current is too large. U850 is a highly integrated PWM controller. Typical
start-up current for U850 is only 30 uA, R841, R842 and R843 are serial circuit to limit current
flow. When current flow through R838 and R839 gets to Pin 3 of U850, with VDD
hold-up capacitor C855, U850 is enough for starting up.
When U850 begins to work Pin8 of U850 will output square wave to drive Q850, and then the
main current flow get to GND bypassing through T850, Q850. Because of the change of current
flow, wires in the other side of T850 will induct current. At the same time, the current inducted by
wires which connected T850 Pin 1 and Pin 2, with components of D852, R855, C855 and C849,
will be supplied to U850 for normal operating.
When the sense voltage across the sense resistor R859, reaches the threshold voltage around
0.85V, the output GATE drive will be turned off. Every time when the output of power supply is
shorted or over loaded, the FB voltage will increase, the build-in PWM output will then be turned off.
Both will prevent the power supply from being overheated under over loading condition. The PWM
duty cycle is determined by this current sense signal and VFB, the feedback voltage. When the
voltage on sense pin reaches Vcomp = (VFB-1.0)/3, a switch cycle will be terminated immediately.
Vcomp is internally clamped to a variable voltage around 0. 85 V for output power limit.
When Q850 are turned off, the main current flow will be consumed through D851, C875 R853 ,
R854 and R855. This will prevent Q850 from being damaged under large current impulse and
voltage spike.

D854 is used to rectify the inducted current. R862 and C862 are used to store energy when
current is reversed. The parts including C863, C864, and R887 are used to smooth the current
waves that are from D854 and D855, and then 12V voltage is supplied. We can see, there have two
parts C862 and R862 paralleling with D857,they have two functions ,One is used to damp the peak
voltage of D857, the other is used for EMI.
D857 is used to rectify the inducted current. R873 and C873 are used to store energy when
current is reversed. The parts including C856, C857, C858 , C876 and L854 are used to smooth
the current waves that are from D857, and then 5V voltage is supplied.C873 and R873 have the
same function with C862 and R862.
In order to limit the 5V and 12V over Spec, we need a sampling circuit to accomplish this
function. At first, use R871 ,R872 and R868 this divider circuit to sample 2.5V, and comparing it to a
reference voltage 2.5,so we will get a differential signal witch can control the current of I851(TL431).
R860,C859 and C871 is frequency compensating circuit witch be able to control feedback loop
speed rate,R857 is else able to accomplish this function, and its main task is getting current for
I851 and I850

4. Power On/Off Sequency
Hardware power On/Off
When power cord plug into AC socket, Power provides 16V and DC_5V.
DC_5V is main voltage for panel and Regulator U103.
DC_3.3V is coming from Regulator U103, DC_3.3v is main voltage for U104. When DC_3.3V
input to U104 and U104 reset circuit active, U104 all registers will be set to default, that means
finish hardware power on.
When pull out power cord from AC socket,the system shut down instantly for no supply
Software power On/Off
- When press power key, U104 #23 receives low pulse, then (TSUM1PEJ-LF-2) U104 will be
wake up and send control signals(at 20,75pin) to on CCFL and switch 5.0v to panel module,
at the same time,U104 make the VGA/DVI cable input signal source display normal on panel
if the VGA/DVI cable input signal is active
- If power ON, U104 #31 (LED_green) will send out low potential, and then LED white on.
- If power saveing, U104 #35 (LED_Amber) will send out low potential, and then LED Amber
on.
- If power ON or power saveing, when press power key, U104 #23 receives low pulse, then
U104 will be sleeping and turn off backlight, at the same time, the panel will lose +5V.
The Panel_Vcc, Backlight_En, CLK/DATA output to panel will follow the following sequency.
