Description

The AP3301 EV1 board is a Quasi-Resonant Flyback converter, operating under CCM and DCM, the valley switching on mode function will be appeared at all DCM region of variable load & high input AC line voltage conditions, it is employed with the peak-current control & multi-mode PWM control functions. Based on above the high performances are optimized & achieved. It is designed to serve as an example for High Efficiency, cost-effective & components less consumer home appliance systems. Its output power is rated at 42W with 12V-3.5A and peak power can be reach to 48W at peak time. Its input power consumption is less than 100mW at no load and meets DOE VI and CoC Tier 2 energy efficiency requirement.
