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.
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.
In addition, NT68673UMFG includes an integrated 8-Bit Microcontroller (MCU). It contains an 8-bit 8031 micro-controller, 5,120-bytes internal data memory, eight 7-bit resolution A/D Converter, 10- channel 8-bit resolution PWM DAC, two16-bit timer/counters, and a UART. Except those, it has two channel hardware DDC solution, and VESA 2Bi/2B+ master/slave I2C bus interface. It can support up to External 512 K Bytes SPI Flash memories for program memory. 2.
4.4 Power On/Off Sequence 4.4.1 Hardware Power ON When power cord is plugged into AC socket, SMPS starts work and provides U105 with VCC5V. When VCC5V inputs, U105 resets circuit active, sets U105 all registers to preset modes, and then monitor goes into stand-by mode. That means hardware power on has been completed. 4.4.2 Software Power ON/OFF When press power key, U105 # 74 recieves low pulse,and then U105 will do the power on/off.
