6.3 DC/DC Converters
The on-board DC/DC converters deliver the following voltages(depending on set execution):
• +5V-SB, permanent voltage for the Stand-by Power system
• +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
• +1V8, voltage for EMMC when TV on
• TUNER_3V3, supply voltage for tuner
• +5V-SW, input intermediate supply voltage for USB Power
• +12V-AUDIO1 for the AUDIO AMP
+1.2V_DEMOD voltage for Demodulator IC channel decoder
• +3V3SBI,voltage for WIFI
