DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
•
+5V_STB, permanent voltage for the Stand-by
•
+3V3SB,voltage for,IR/LED reciver,Key board.and WIFI
•
+12V, input from the power supply for the panel common
(active mode)
•
PVDD from the power +12V_AU for the AUDIO AMP
•
+3V3_TUNER, supply voltage for tuner
•
+5V-USB, input intermediate supply voltage for USB
