7.3 DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
• +5V-STANDBY, permanent voltage for the Stand-by
controller, LED/IR receiver and controls
• +12V, input from the power supply for the panel common
(active mode)
• +24V, input from the power supply for audio amplifier
• +1V2, core voltage supply for MT5580
• +1V5, supply voltage for DDR2 (diagram B03B)
• +3V3, general supply voltage
• +3V3-TUN, supply voltage for tuner
• +5V-USB, input intermediate supply voltage for USB
• +3V3 from the power supply for the scaler IC MT5580
• +12V input from the power supply for the ambilight
common
• +3V3-DVBS, clean voltage for DVB-S2 channel decoder
• +1V2-DVBS, core voltage for DVB-S2 channel decoder.
Figures gives a graphical representation of the DC/DC
converters with its current consumptions:
