DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
•
+3.5V-STANDBY,permanent voltage for the Stand-by
controller.
•
+12V, input from the power supply for the panel common
(active mode).
•
+12V, input from the power supply for the AMP.
•
+1V2, 1V8,3V3 from the DC/DC for the scaler IC Marvell
•
+1V5, supply voltage for DDR3
•
+3V3, general supply voltage
•
+5V, supply voltage for USB and CAM
•
+3V3-TUN, supply voltage for tuner
•
+5V-USB, input intermediate supply voltage for USB
•
+3V3-DVBS, voltage for channel decoder
•
+1V2-DVBS, voltage for Analog demodulator
Figures gives a graphical representation of the DC/DC
converters with its current consumptions:
