EVAL_5QR2270AZ_33W1

综述

33W ultra-wide (three-phase) input-range, off-line isolated power supply using ICE5QR2270AZ and IPD80R2K4P7

This is a 33W open frame isolated off-line switching power supply evaluation board, targeted for power supply with three-phase input or an ultra-wide input voltage range. The board demonstrates the possibility of extending voltage working range up to 1500V by cascading an external MOSFET. It features the 5th generation quasi-resonant CoolSETTM (ICE5QR2270AZ), together with Infineon’s 800V CoolMOSTM P7 superjunction MOSFET (IPD80R2K4P7).

Summary of features

  • Up to 33W continuous power
  • Ultra-wide input range 135~560VAC
  • Output: 24V/1.38A
  • Full load efficiency >87%
  • Line input over voltage, brown in/out, output over-voltage, short circuit and overload protection

Summary of benefits

  • Ease-of-scaling with Infineon wide CoolSET™ and CoolMOS™ portfolio
  • High efficiency with quasi-resonant switching scheme
  • Cost-efficient 800V MOSFET in DPAK SMD package
  • Comprehensive protection
