• Circuit
For under 21inch, used for both AV processor (main power supply) and BL inverter power supply.
For larger than 26inch, 2-power supply system is usually used (one is for BL inverter use, and the other is for AV processor use).
• Secondary-side diode voltage
In case of fl yback circuit, diode voltage should be 100V and above for 12V output (when PFC output is 380V).
In case of half-bridge circuit, diode voltage should be 100V and above for 24V output (when PFC output is 380V).
