DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
•
+5V2-STANDBY, permanent voltage for the Stand-by
controller, LED/IR receiver and controls
•
+12V, input from the power supply for the panel common
(active mode)
•
+24V, input from the power supply for audio amplifier
•
+1V1, core voltage supply for MT5366; has to be started up
first and switched “off” last
•
+1V2, supply voltage for power supply for the scaler IC
MT5366
•
+1V5, supply voltage for DDR3 (diagram B03B)
•
+3V3, general supply voltage
•
+5V-TUN, supply voltage for tuner
•
+5V-USB, input intermediate supply voltage for USB
•
+3V3 from the power supply for the scaler IC MT5366
•
+3V3-DVBS, clean voltage for DVB-S2 channel decoder
•
+1V-DVBS, core voltage for DVB-S2 channel decoder.
