7.3 DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
• +5V-STANDBY,(transform from 12V). permanent voltage
for the Stand-by controller, LED/IR receiver and controls.
• +12V, input from the power supply for the panel common
(active mode)
• +12V, input from the power supply for the AMP
• +1V2, from the power supply for the scaler IC MT5580
• +1V5, supply voltage for DDR2
• +3V3, general supply voltage
