Description

This document is a reference design for a 3 W IoT off-line isolated power supply using the latest Infineon fifth-generation Fixed Frequency (FF) CoolSET™ ICE5AR4770AG. The power supply is designed with a universal input compatible with most geographic regions, and isolated output (+5 V/0.6 A). Highlights of the 3 W IoT off-line isolated power supply: - Very small form-factor design - Simplified circuitry with good integration of power and protection features - Auto-restart protection scheme to minimize interruption and enhance end-user experience

Features

  • 100kHz maximum switching frequency with 700V integrated MOSFET
  • Power delivery of up to 15W with universal wide input range (85~300VAC) DCM design
  • Brown in protection, fast and robust start-up operation with cascode configuration
  • 3 level selectable entry/exit active burst mode profile (optional)
  • Built-in digital soft-start
  • Cycle by cycle peak current limitation
  • Support both DCM and CCM operation with slope compensation
  • Integrated error amplifier to support direct feedback typical with non-isolated flyback topology
  • Digital frequency reduction with decreasing load for higher efficiency
  • Adjustable line input over voltage protection (optional)
  • VCC and CS pin short to ground protection
  • OLP, output short, OTP with hysteresis and VCC over/under voltage protection
  • Auto-restart for all protection features

Typical applications

  • Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE / Offline aux SMPS for server, PC power, aircon, refrigerator and audio
