Features

  • a unique short-time heavy load operation mode, which delivers up to 15w output power for a programmed time. This feature allows the smart meter's AC/DC power supply to be designed at a regular power level without being over-designed for 2x power in the transmission mode, which greatly reduces system cost. The RAA223183 also has a cap-saving feature for single-phase.

RAA223183 1000V Off-line Flyback Regulator Datasheet The RAA223183 is an off-line Flyback regulator with a 1000V integrated MOSFET, designed for high-reliability application of single-phase and 3-phase smart meter power supplies and other generally isolated power supplies. The RAA223183 can deliver up to 7W power from the single-phase and 11W from 3-phase universal inputs. The RAA223183 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 with the communication of the smart meter.
