• LED backlight:
- side-view LED without scanning: PSL power panel
- side-view LED with scanning: PSLS power panel
- direct-view LED without 2D-dimming: PSL power panel
- direct-view LED with 2D-dimming: PSDL power panel.
PSL stands for Power Supply with integrated LED-drivers.
PSLS stands for a Power Supply with integrated LED-drivers with added Scanning functionality (added microcontroller).
PSDL stands for a Power Supply for Direct-view LED backlight with 2D-dimming.
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
