Overview

Description

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.

Features

  • Flyback regulator with 1000V 9Ω MOSFET
  • Single 400V bulk capacitor for single-phase input up to 460VAC
  • Frequency doubling for heavy load operation (up to 15W in single-phase and 21W and above in 3-phase), with programmable duration (maximum time depends on thermal capability)
  • Valley switching to reduce switching losses
  • Programmable constant frequency PWM operation
  • Burst mode operation at light load
  • Protection features: Short-circuit protection (SCP), overload protection (OLP), input undervoltage lockout (VinUV), Input OVP, VCC overvoltage protection (VccOV), VCC undervoltage lockout (VccUV) and over-temperature protection (OTP).
  • 4KV surge compliance per IEC 61000-4-5 with cap-saving operation
