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, 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
•
+1V5, from the power supply for the scaler IC NT72453
•
+1V1, from the power supply for the scaler IC NT72453
•
+3V3, from the power supply for the scaler IC NT72453
•
+1V5, supply voltage for DDR2 (diagram B03B)
•
+3V3, genenal supply voltage
•
+5V, supply voltage for USB and CAM
•
+3V3-TUN, supply voltage for tuner
•
+3V3 from the power supply for the scaler IC NT72453
•
+5V_SW, input intermediate supply voltage for USB
•
+3V3_T2, voltage for Tuner single decoder
•
+1V2_T2, voltage for Tuner single decoder
