10 pcs : RAA2231814GSPHA0 - Switching Controllers 900V Fly-back Regulator, 13-ld SOIC, T&R, 2500 piece reel

RAA223181 900V Off-Line Flyback Regulator Renesas Electronics RAA223181 900V Off-Line Flyback Regulator is optimized for high input voltage and high-reliability applications such as smart meter power supplies and other general isolated power supplies. The RAA223181 operates in Discontinuous-Conduction-Mode (DCM) with constant switching frequency at full load. The device is inherently stable with an easy feedback loop design while switching at constant frequency without interfering with the communication of the smart meter. The RAA223181 enters burst-mode operation at light loads to reduce the IC power consumption while keeping the burst frequency less than 3kHz to avoid interference to the PLC frequency band.
