600W DC-DC/LLC stage, 400V/12VDC, 97.8% peak efficiency
This 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: 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 analog or XMC™ microcontroller (XMC4200) in the digital version.
