ICE5ASAG

概要

Infineon's latest 5th generation fixed frequency flyback PWM controller offers high performance and a comprehensive suite of protection to increase system robustness.

特長

  • 100kHz maximum switching frequency
  • 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 pin short to ground protection
  • OLP, output short, OTP with hysteresis and VCC over/under voltage protection
  • Auto-restart for all protection features

利点

  • Reduce BOM count and cost with integrated line input over voltage protection and error amplifier
  • Increase mid and light load efficiency with digital frequency reduction
  • High power delivery with slope compensation for CCM operation

推奨アプリケーション例

  • Offline aux SMPS for server, PC power and major home appliances (e.g. air conditioning, washing machines and refrigerator)
  • Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE
