4. Circuit Description
4.1 Switching Mode Power Supply
4.3.1 AC Current Input Circuit
P801 is a connector for connecting AC Power. F801 is a fuse to protect all the circuit. AC input
voltage is from 90v to 264V. R801,R831 and R802 joined between two inputting main circuit to
prevent man from shock. L801 is used to clear up low frequency wave. C801 and C802 are used to
discharge the waves that L801 produced. High frequency waves are damped by C801 and C802.
D801 is a rectifier which composed of 4 build-in diodes, it inverts AC to DC.

4.3.2 High Voltage to Low Voltage Control Circuit


C804 is used to smooth the wave from rectifier. IC802 is a highly integrated PWM controller.
When rectified DC high voltage is applied to the HV pin during start-up, the MOSFET Q804 is initially
off, and the Vcc pin capacitor is charged. When the Vcc pin voltage reaches approximately 10V, the
control circuitry is activated and the soft-start begins. The soft-start circuit gradually increases the duty
cycle of the MOSFET from zero to the maximum value over approximately 4ms. a stably output
voltage Will be increase about 40ms later, and then feedback a continue current through the IC801
which control the output of the PWM IC. If no external feedback/supply current is feed into the FB
pin by the end of the soft-start, the current Set point will be above the fault level, FAULT flag is raised,
if the FAULT duration exceeds 80ms, the output controller disable
Resistor R808, R809, R810, R811 are for line over voltage shutdown(OVP) and Brown Out
Protection (BOP)
When PWM is turned off, the main current flow will be consumed through R804 and D802, This
will prevent MOSFET Q804 from being damaged under large current impulse and voltage spike.
D803 and C807 to provide internal Auxiliary voltage to Vcc pin during normal operation.
Otherwise, error amplifier and feedback current input the FB pin for duty cycle control.

4.3.3 DC_5V and DC_14V Output Circuit


For DC 5V, D805 is used to rectify the inducted current. R828 and C814 are used to store
energy when current is reversed. The parts including C818, C822, C820,L803 are used to smooth
the current waves.
For DC 14V, D803 is used to rectify the inducted current. R827 and C813 are used to store
energy when current is reversed. The parts including C815, C817 and L802 are used to smooth the
current waves.

4.3.4 Feedback and OVP Protect Circuit


Pin R of IC803 is supplied 2.5-v stable voltage. It connects to 5V and 14V output through
R822, R823 and R824. R822, R823 and R824 are output sampling resistor. When the sampling
voltage more than 2.5V or less than 2.5V, current of FB IC802 will change, this can change the
voltage from T801.

4.2 Inverter Circuit
1. R503, ZD501, R502, Q501 components convert +14V voltage into +5.0V voltage, and the voltage
supply to IC501. The extra PWM pulse signal (BRIGHTNESS signal) input to control IC through R512,
R514, C510, The LCT pin is set to a DC voltage of 0.7V by using a resistor divider(R507, R516), change
the duty of PWM pulse, will regulate the lamp current. The ON/OFF voltage connect to pin10 of IC501
through D501, R501, A voltage of 2V to pin10 of IC501 enables the IC and activates the striking timer.
The SSTCMP pin of IC501 performs the soft function, the C511 set the time of SST. The operation
frequency determined by external capacitor C512, C521 and resistor R508 connected at CT pin of IC501.
C515 connect the TIMER pin of IC501, the capacitor to set striking time and shunt down delay time.
DRV!, DRV2 output for power MOSFET U501, U502.
2. OZ9938 provides two drive signals for U501, U502, and they work in push pull topology driving, two
transformers are connected in parallel with each transformer driving two lamps in series. Turning each
N-Channel MOSFET “on/off” complementarily, produces an alternating current through the transformer
primary and secondary. The “on” duration of the switches determines the amount of energy delivered to
the CCFLs. R504, C504, R505, C505, R532, C529, R530, C522 are snubber networks, they suppress
Voltage transient spike in drain of power MOSFET.
3. R506, R510, C509, C513, C514, R525, R531, C528, C525, and C527 are connected between high

4.3.3 VGA Input


Signal R, G, B input through CN102 #1, #2, #3. Signal HSYNC and VSYNC input through CN102 #13 and
#14, and C129, R135, C130, R136 filtering. Then the analog signal enters U105, and then U105 deals with it
internally. In addition, D104, D105, D102,D103 (the four are BAV99), ZD102, ZD103, ZD104, ZD105, ZD106
(they are constant voltage diode of 6V2) are ESD protector. Signal DDC-SCL inputs via CN102 #15, and then
passes through ZD106 for ESD protection, goes into U105 #41. Signal DDC-SDA inputs via CN102 #12, and
then passes through ZD105 for ESD protection, goes into U105 #42. CN102 #5 is defined as cable detect pin,
this detector realizes via R125,The PC-5V of U105 is supplied by PC via CN102 #9 with D101.

Pin No. Symbol I/O Description

Open lamp voltage feedback input 2. Connect a capacitive voltage

divider from the hot terminal of the lamp to ground. Connect this pin to

the tap on the divider and a bias resistor to VCC. In multi-lamp

application, connect a diode from each lamp capacitive voltage divider

which is in-phase to each other to this pin. If the peak voltage value at

OV2 pin exceeds +13V, the controller will treat this as lamp overvoltage

1 OV2 I condition. A pulse of current will pull-down on the COMP pin to regulate

the lamp voltage. The burst dimming signal will be ignored and the Fault

Timer will start ramping up. This signal is also used for short circuit
protection. If the voltage at OV2 is always above 4.9V, the controller will

treat this as a short circuit condition after a certain delay. The Fault Timer

will start ramping up. In single lamp application, connect this pin to OV1

pin.

Lamp current feedback 1. Connect this pin to the current sense resistor.

In multi-lamp application, connect a diode from this pin to each lamp

current sense resistor which is in-phase to each other. These diodes

forms an AND gate with an internal 60uA pull up current source.

Combined with the lamp current feedback signal from LI2, the signal is
2 LI1 I
fed to the internal error amplifier. Selecting the feedback resistors can

easily program the lamp current. The signal is also used for open lamp

protection. If the voltage at LI1 is always below 1.15V, the controller will

treat this as an open lamp condition after a certain delay. The burst

dimming signal will be ignored and the Fault Timer will start ramping up.

VX2433wm-1
ViewSonic Corporation 48 CONFIDENTIAL – DO NOT COPY VX2433wm-CN
In single lamp application, connect this pin to LI2 pin.

Lamp current feedback 2. The function of this pin is same as LI1. In

3 LI2 I single lamp application, connect this pin to LI1. In multi-lamp application,

this pin is used for lamp current feedback which is out-of-phase of LI1.

Feedback Compensation Node. Connect a compensation capacitor from

this pin to GND. This pin is also used for IC enable control. A logic low
4 COMP I
(below 0.5V) input turns off the IC. The enable logic input signal should

have open collector (OC) structure.

Fault Indicator. Connect a capacitor from this pin to GND to program the

5 FT I open lamp and short lamp protection delay time. When the voltage on

this pin reaches 1.2V, the IC will shutdown until it is enabled again.

Switching Frequency Set. Connect a resistor from this pin to GND. This
6 FSET I
resistor sets the operating frequency of the MP1009.

Burst Repetition Rate Setting. Connect a resistor and a capacitor from

this pin to GND. If the burst dimming is to be controlled by an external


7 BOSC I
logic signal, connect BOSC to VCC and apply the logic signal to the

DBRT pin.

Burst-Mode (Digital) Brightness Control Input. The voltage range of 0V to

1.2V at DBRT linearly sets the burst-mode duty cycle from minimum to

8 DBRT I 100%. The minimum burst dimming duty can be programmed by BOSC

resistor and capacitor. If burst dimming is not used, connect DBRT to

VCC.

Input Power Rail. Decouple this pin to GND with >1μF ceramic capacitor.
9 VIN I
It is desirable to add a 10Ÿ resistor between VIN pin and the input bus.

Output Bootstrap. BT provides gate driver bias for the high-side


10 BT O
MOSFET. Connect a capacitor from BT to SW.

High-Side MOSFET Gate Output. Connect TG to the gate of the


11 TG O
high-side, external power MOSFET.

Bridge Output. Connect SW to the source of the high-side MOSFET and


12 SW O
the drain of the low-side MOSFET.

Voltage Rail Output. VCC provides power supply for the low-side gate

13 VCC O driver and the internal control circuitry. Bypass VCC to GND with a

ceramic capacitor.

Low-Side MOSFET Gate Output. Connect BG to the gate of the low-side


14 BG O
MOSFET.
