DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
•
+3V5-SB, permanent voltage for the Stand-by Power
system and WIFI
•
+3V3-STANDBY,voltage for IR/Key board
•
+12V, input from the power supply for the panel
common(active mode)
•
+12V, input from the power supply for LNB supply
•
+3V3-EMMC, +V-EMMC-IO, voltage for EMMC when TV
on
•
+1V5-DDR, +VREF-A2-DQ,, +VREF-A2-CA, voltage for
DDR
•
TUNER_3V3, supply voltage for tuner
•
+5V-SW, input intermediate supply voltage for USB Power
•
+12V-AUDIO1 for the AUDIO AMP
•
+3.3VA_T2, +1.2V_T2 voltage for Demodulator IC channel
decoder
•
+3V3-WIFI,voltage for WIFI
