Evaluation board shows how to design the half-bridge LLC stage of a server SMPS with the target to meet 80+ Titanium® standard efficiency requirements. For this purpose, the following technologies has been used namely 600V CoolMOS™ C7 SJ MOSFET IPP60R180C7 on the primary side and OptiMOS™ 40V low voltage power MOSFET in SuperSO8 BSC010N04LS in the synchronous rectification secondary stage, in combination with QR CoolSET™ ICE2QR2280Z, EiceDRIVER™ 2EDL hi-low side driver 2EDL05N06PF, EiceDRIVER™ 2EDN low side gate driver 2EDN7524F and an LLC controller ICE2HS01G for the analogue or XMC™ microcontroller XMC4200 in the digital version. Targeted application is high efficiency Titanium® server SMPS. Target application is power supply.
