4. Circuit Description
1. Power supply (DC/DC Converter)
This brick convert is the 110-220AC input voltage to 12V AND 5V output for inverter,
audio, panel and system controller use.
It consists of a PWM IC (CM0565R, U101)
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 WXGA into WXGA
resolution that panel can acknowledge.
GENERAL DESCRIPTION
The TSUM17AK is a high performance, and fully integrated graphics processing IC solution
for LCD monitors with resolutions up to WXGA. 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,
and LVDS display interface. To further reduce system costs, the TSUM17AK also integrates
intelligent power management .
