Overview

TopologyLLC Resonant Converter
Input voltage400 V
Switching frequency30-1000 kHz
Output 112 V / 25 A
IC revision1.0

Description

The evaluation board presented is a 300 W LLC Converter with 400 VDC input and 12 V output. It is controlled by Infineon’s 2nd generation half-bridge LLC controller ICE2HS01G. The ICE2HS01G is specially designed for high efficiency applications with synchronous rectification (SR) control on the secondary side. With new driving techniques, SR can be realized for a half-bridge LLC converter operated with secondary switching current in both CCM and DCM conditions.

Features

  • Resonant mode controller for Half-bridge LLC resonant converter with synchronous rectification
  • 20-pin DSO package
  • 30 kHz to 1 MHz switching frequency
  • Adjustable minimum switching frequency with high accuracy
  • 50% duty cycle for both primary and secondary gate drives
  • Adjustable dead time with high accuracy
  • Driving signal for synchronous rectification which supports full operation of a Half-bridge LLC resonant converter
  • Internal and External disable functions for synchronous rectification
  • Mains input under voltage protection with adjustable hysteresis
  • Three levels of overcurrent protection for enhanced dynamic performance
  • Open-loop/overload protection with adjustable blanking time and restart time
  • Adjustable over-temperature protection with latch-off
  • External latch-off enable pin

Typical applications

  • PC, LCD/PDP TV
  • Server SMPS
