Beschreibung

This document is a reference design for a 15 W auxiliary power supply for an invertized air-conditioner unit with 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 two outputs (+12 V/1 A isolated, +15 V/150 mA non-isolated) on a single-layer PCB. The PCB has a provision to add a linear regulator to support a third output (e.g. +5 V), which is connected to a +12 V output.

Eigenschaften

  • 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

Typische Anwendungen

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