DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
•
+5V-STANDBY,(transform from 12V). permanent voltage
for the Stand-by controller, 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 AMP
•
+1V2, from the power supply for the scaler IC MT5580
•
+1V5, supply voltage for DDR2
•
+3V3, general supply voltage
•
+5V, supply voltage for USB and CAM
•
+3V3-TUN, supply voltage for tuner
•
+5V-USB, input intermediate supply voltage for the USB
Power
•
+3V3 from the power supply for the scaler IC MT5580
•
+3V3-DVBS, clean voltage for DVB-T2 channel decoder.
•
+1V2-DVBS, core voltage for DVB-T2 channel decoder.
Figures gives a graphical representation of the DC/DC
converters with its current consumptions:
