EVAL_1K4W_ZVS_FB_CFD7

概要

Full-bridge solution for server and industrial SMPS systems

This is a high-performance evaluation board example with a complete Infineon solution, including high voltage and low voltage power MOSFETs, controllers and drivers. This board demonstrates a very effective way to design the high voltage DC-DC stage of a server or industrial SMPS fulfilling the highest standard of efficiency and reliability. The overall best-in-class performance is achieved because of a mix of proper control techniques and best-in-class power device selection. Key Infineon products used to achieve this performance level include, 600V CoolMOS™ CFD7 SJ MOSFET (IPP60R170CFD7), EiceDRIVER™ 2EDN advanced dual-channel gate driver IC (2EDN7524F), OptiMOS™ 5 80V synchronous rectification MOSFETs (BSC026N08NS5),  XMC™ microcontroller (XMC4200-F64K256 BA) and an auxiliary supply solution featuring off-line SMPS current mode controller IC (ICE5QSAG) with an integrated 800 V CoolMOS™ device.
