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 systemI
• +3V3-STANDBY,voltage for IR/Key board
• +16V, input from the power supply for the panel common(active mode)
• +12V, for the panel common(active mode)
• TUNER_3V3, supply voltage for tuner
• +5V, 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
