Overview

Description

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.

Features

  • Flyback regulator with 900V 10Ω MOSFET
  • Single 400V input capacitor for input up to 450VAC
  • Frequency doubling for heavy load operation (up to 12W), with programmable duration < 100ms
  • Valley switching to reduce switching losses
  • Programmable constant frequency DCM operation (recommended range 50kHz ~100kHz)
  • 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)
