Notes:
Note1. Ripple/noise Performed by 20M Hz bandwidth in oscilloscope.
Note2. Applied 0.1uF SMD chip capacitor and 10uF electrolytic capacitor across
Note3. 70A Peak current for 50mS
Note4. Audio
Note5. 24V for inverter
Note6. ON/OFF control: If PWR-ON low that 5VS on, and 5V, 12V, 24V off.
Note7. Stand by Power under 5W at 5VS at input voltage 200~240VAC and
47~63Hz.
Note8. Without PFC, but must be reserve passive PFC.
Note9. If design to adopt local vendor MOSFET, PWM IC, Output rectifier, please
discuss with BenQ RD.
