Overview

Description

The RAA223182 is an off-line Flyback regulator with a 1000V integrated MOSFET, designed for high input voltage applications such as 3-phase electric meter power supplies and other generally isolated power supplies. The RAA223182 can deliver up to 11W from the universal 3-phase input voltage.

Features

  • Flyback regulator with 1000V 9Ω MOSFET
  • Frequency doubling for heavy load operation (21W and above), for a programmable duration (maximum time depends on thermal capability)
  • Fault-tolerant input overvoltage protection
  • 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).
