30W flyback power adapter design

1206 red anti-stick

MOS power IC full range

Overview:
The 30W flyback power adapter solution supports AC input voltages from 85V to 265V for use in the global market. Its main selling points are: 6uA low starting current, built-in over temperature, over voltage, under voltage, overload and feedback open circuit protection, no audible noise during operation, excellent EMI performance.
