6.3 DC/DC Converters
The on-board DC/DC converters deliver the following voltages(depending on set execution):
• PVDD from the power 12V_AMP for the AUDIO AMP.
• 3V3SB, permanent voltage for the Stand-by controller, LED/IR, keyborad receiver and controls.
• +12V, input from the power supply for the panel common(active mode)
• +12V, input from the power supply for the AMP
• DDRV supply voltage for DDR
• TUNER3.3V, supply voltage for tuner
• +5V_SW, input intermediate supply voltage for the USB Power
• 3V3SB, from the power supply for the scaler IC MT5561
• DVDD3V3, +1V2,clean voltage for Demodulator IC channel decoder
