7.3 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
