RAA223181
RAA223181 is 900V Off-Line Flyback Regulator manufactured by Renesas.
900V Off-Line Flyback Regulator
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 munication of the smart meter. At light load, RAA223181 enters burst mode operation to reduce the IC power consumption, while keeping the burst frequency less than 3kHz to avoid interference to the PLC frequency...
