RAA223181 900V Off-Line Flyback Regulator

RAA223181 900V Off-Line Flyback Regulator Datasheet The RAA223181 is an off-line Flyback regulator with a 900V integrated MOSFET, designed for high input voltage and high reliability application of smart meter power supplies and other general isolated power supplies. The RAA223181 operates in DCM with constant switching frequency at full load. The system is inherently stable with an easy feedback loop design, while switching at constant frequency without interfering the communication of the sm.

RAA223181 Features

* a unique short-time heavy load operation mode, which delivers up to 12W output power for a programmed time period. This allows the smart meter power supply to be designed at regular power level without being over-designed for 2x power in the transmission mode, which greatly reduces system cost. RAA2
