This document is an engineering report of a universal input 20 W 5 V off-line flyback converter power supply utilizing F3R80 CoolSET™ ICE3AR2280VJZ. The application evaluation board is operated in Discontinuous Conduction Mode (DCM) and is running at 100 kHz switching frequency. It has a single output voltage with secondary side control regulation. It is especially suitable for small power supply such as DVD player, set-top box, game console, charger and auxiliary power of white goods, server, PC and high power system, etc. The ICE3AR2280VJZ is the latest version of the CoolSET™. Besides having the basic features of the F3R CoolSET™ such as Active Burst Mode, propagation delay compensation, soft gate drive, auto restart protection for major fault (VCC over voltage, VCC under voltage, adjustable input OVP, over temperature, over-load, open loop and short opto-coupler), it also has the BiCMOS technology design, selectable entry and exit burst mode level, adjustable AC line input over voltage protection feature, built-in soft start time, built-in and extendable blanking time and frequency jitter feature, etc. The particular features are the Best-in-Class low standby power and the good EMI performance.


  • 800 V avalanche rugged CoolSET™ with startup cell
  • Active Burst Mode for lowest standby power
  • Selectable entry and exit burst mode level
  • 100kHz internally fixed switching frequency with jittering feature
  • Auto restart protection for over load, open Loop, VCC under voltage and over voltage and over
  • temperature
  • Over temperature protection with 50 °C hysteresis
  • Built-in 10 ms soft start
  • Built-in 20 ms and extendable blanking time for short duration peak power
  • Propagation delay compensation for both maximum load and burst mode
  • Adjustable input OVP
  • Overall tolerance of current limiting < ±5%
  • BiCMOS technology for low power consumption and wide VCC voltage range
  • Soft gate drive with 50 Ω turn-on resistor
