1. Power supply (DC/DC Converter)
This brick convert is the 110-220AC input voltage to 12V AND 5V output for invert use and panel
use and system controller use.
It consists of a PWM IC (FP5001, I804), flywheel diode (MS22,D812), buck choke (L812) and
capacitor C817.
5V Out put at 5,6 pin
VCC 12V In put at L801,L812 pin
2. Scaling controller
The ADC is to convert RGB analog signal to digital signal that scaling chip can acknowledge.
The HSYNC input receives a logic signal and provides the frequency reference for pixel clock
generation.
The scaling IC is to converts the input signal ranging from VGA to SXGA into SXGA resolution that panel
can acknowledge.
GENERAL DESCRIPTION
The I108TSU56AK is a high performance, and fully integrated graphics processing IC solution for
LCD monitors with resolutions up to SXGA. It is configured with an integrated triple-ADC/PLL, a
high quality scaling engine, an on-screen display controller, a built-in output clock generator, an
integrated DVI receiver, and LVDS display interface. To further reduce system costs, the
TSU56AK also integrates intelligent power management.
3. MTV312M64
The I106 MTV312M micro-controller is an 8051 CPU core embedded device especially tailored
for CRT/LCD Monitor applications. It includes an 8051 CPU core, 1024-byte SRAM, 14 built-in
PWM DACs, VESA DDC interface, 4-channel A/D converter, and a 64K-byte internal program
Flash-ROM.
A “CMOS output pin” means it can sink and drive at least 4mA current. It is not recommended to
use
Such pin as input function. A “open drain pin” means it can sink at least 4mA current but only
drive 10~20uA to VDD. It can be used as input or output function and needs an external pull up
resistor
