Beschreibung

This document is a reference design for an 18 W adapter power supply for a set-top box with the latest fifthgenerationInfineon Fixed Frequency (FF) controller (ICE5GSAG) and CoolMOS™ P7 (IPN70R1K2P7S). The powersupply is designed with a universal input compatible with most geographic regions, and an isolated output (+12V/1.5 A) on a single-layer PCB.Highlights of the adapter for a set-top box are:- Up to 18 W continuous output power in a universal input voltage range design- High average efficiency and low standby power to meet the European Union’s Code of Conduct (CoC)Version 5 Tier 2 single-voltage external AC-DC power supply basic-voltage requirements- Comprehensive protection feature controller in DSO-8 package and high ESD ruggedness 700 V CoolMOS™P7 superjunction MOSFET- Auto-restart protection scheme to minimize interruption and enhance end-user experience

Merkmale

  • 125kHz 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 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
