Theory of Operation

1. AC/DC Adapter

Input voltage : 90 ~ 264 Vac, 50/60 Hz

Input current : Max 1.5A (Vin : 90Vac , 50Hz)

Inrush current : 15A peak (At 115Vac Max . Load)

30A peak (At 230Vac Max. Load)

Output voltage : 18Vdc (At 115Vac / 230Vac Max , Load)

Output current : 2.5Adc (Max. Load)

Over Current Protection : 3.0 ~5.0Adc (At 115Vac / 230Vac)

2. DC/AC INVERTER

Input voltage : DC 12V

Input current : 2.0A(Max)

Output current : 15.0mA(Max) , 3.0mA(Min)

Frequency(switching) : 40KHz

Output power : 4.5W(Max)

On/off control voltage : 5.0V

3 . Video circuit

Input signals are amplified by a preamp TDA9206, then a gain of R.G.B Signal are changed by

controlling Color Temperature(OSD Adjust). Amplified video signals are input to the

ADC(Analog to Digital Converter) and converted to digital signals.

Again,digitized video signals are input to the MX88271(or MX88281:Video Processor), and

output to the LCD module as synchronized timing after it execute the function of Zooming,

Scaling, Frame Rate Conversion, Brightness, Contrast, Dithering, Gamma compensation etc...

4. Clock(H-size)

Clock generator, CXA3106A(PLL Chip), is controlled by MCU.

Pixel clock is changed according to each video mode.

5. DPMS MODE
