EVAL_600W_12V_LLC_CFD7

Overview

The EVAL_600W_LLC_12V_CFD7 evaluation board shows how to design a half-bridge LLC stage of a server SMPS with the target to meet 80+ Titanium Standard efficiency requirements. For this purpose the following components have been used: latest 600V CoolMOS™ CFD7 SJ MOSFET technology (IPP60R170CFD7) on the primary side and OptiMOS™ 40V low voltage power MOSFET (BSC010N04LS) in the synchronous rectification secondary stage, in combination with quasi-resonant CoolSET™ (ICE2QR2280Z), EiceDRIVER™ Compact 2EDL hi-low side driver (2EDL05N06PF),  EiceDRIVER™ 2EDN low side gate driver (2EDN7524F) and analog LLC controller (ICE2HS01G).

Summary of features

  • Best-in-class high voltage and low voltage MOSFETs for LLC application
  • Analog control
  • Optimized magnetic design (transformer and resonant tank)
  • Accurate driving scheme of both primary and secondary MOSFETs

 

Summary of benefits

  • 80+ Titanium Stardard achieved
  • Optimal use of CoolMOS™ and OptiMOS™ best-in-class devices
  • ZVS achieved in the entire load range
  • Safe operation of high voltage MOSFETs in critical LLC operations

Target applications

  • Server SMPS, industrial SMPS, Industrial battery chargers
