ICE5AR4780BZS

Overview

Infineon's latest 5th generation fixed frequency CoolSET™ offers high performance and integration of latest generation of 800V CoolMOS™ P7 superjunction MOSFETs in DIP-7 package (Product qualified according to JEDEC standard).

Summary of Features

  • 100kHz maximum switching frequency with 800V 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
  • VCC pin short to ground protection
  • OLP, output short, OTP with hysteresis and VCC over/under voltage protection
  • Auto-restart for all protection features

Benefits

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

Potential Applications
