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)
•
+12V, input from the power supply for the amplifier
•
+1V5, supply voltage for DDR
•
+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 MST6852LP
