This evaluation board shows how to design a halfbridge LLC stage of a server SMPS with the target to meet 80+ Titanium standard efficiency requirements. On this purpose there has been applied latest 600V CoolMOS™ P7 power MOSFET technology (IPP60R180P7) on the primary side and OptiMOS™ low voltage power MOSFET in SuperSO8 (BSC010N04LS) in the synchronous rectification secondary stage, in combination with QR CoolSET™ (ICE2QR2280Z), hi-low side driver 2EDL05N06PF, 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
- 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
- Server SMPS
- Industrial SMPS
- Industrial battery chargers
