RAA223011 Primary-Side-Regulated Flyback Converter Demo Board, 85VAC to 265VAC Input and 12V 400mA Output

The RTKA223011DR0080BU demonstration board is an ultra-low standby power off-line flyback converter. It demonstrates the features of the low-cost, high-performance RAA223011 700V AC/DC switching regulator in an isolated AC/DC convertor configuration operating from a universal input of 85VAC to 265VAC. It provides a 12V output capable of 400mA. The board uses primary side regulation without the use of an optocoupler.
