4. POWER STAGE
The DC voltages required at various parts of the chassis and inverters are provided by a
main power supply unit. The power supply generates 33V, 24V, 12V, 5V, 3,3V and 5V,
3,3V stand by mode DC voltages. Power stage which is on-chasis generates 1,26V
stand by voltage and 8V, 2,6V, 1,8V and 1V supplies for other different parts of the
chassis.
5. MICROCONTROLLER (MSTAR)
5.1. General Descripction
The MST6WB7GQ-3 is a high performance and fully integrated IC for multi-
function LCD monitor/TV with resolutions up to full HD (1920x1080). It is
configured with an integrated triple-ADC/PLL, an integrated DVI/HDCP/HDMI
receiver, a multi-standard TV video and audio decoder, two video de-interlacers, two
scaling engines, the MStarACE-3 color engine, an on-screen display controller, an 8-bit
MCU and a built-in output panel interface. By use of external frame buffer, PIP/POP is
provided for multimedia applications. Furthermore, 3-D video decoding and processing
are fulfilled for high-quality TV applications. To further reduce system costs, the
MST6WB7GQ-3 also integrates intelligent power management control capability for
green-mode requirements and spread-spectrum support for EMI management.
