7.3 DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
• +5V-STANDBY, permanent voltage for the Stand-by
controller
• +3V3-STANDBY, power supply for LED/IR receiver and
controls
• +12V, input from the power supply for the panel common
(active mode)
• +24V, input from the power supply for the amplifier
• +1V2, from the power supply for the scaler IC MST6931
• +1V8, supply voltage for DDR2 (diagram B03B)
• +3V3, general supply voltage
• +3.3V-TUN, supply voltage for tuner
• +3.3V, supply voltage for Headphone AMP
• +5V-USB, input intermediate supply voltage for USB
Power
• +3V3 from the power supply for the scaler IC MST6931
