Beschreibung

This document is a reference design for an 8 W auxiliary SMPS for air-conditioner with the latest Infineon fifth generation fixed-frequency CoolSET™ ICE5AR4770BZS. The power supply is designed with a universal input compatible with most geographic regions and isolated output (+12 V/1.25 A and +5 V/0.50 A) as typically employed in most home appliances.

Eigenschaften

  • 100kHz maximum switching frequency with 700V integrated MOSFET
  • Power delivery of up to 8W 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
  • 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

Typische Anwendungen

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