The output diode rectifier / SR MOSFET voltage rating is determined using Equation 19:
The RMS currents through the output SR MOSFET is given with Equation 20:
To reduce the losses in the synchronous rectifier, the 4-pcs CSD18510Q5B with very low RDS(on) and Qg is used in parallel. Each MOSFET used one dual-channel, non-isolated driver, the UCC27524, to reduce the conduction losses in the LLC output stage.
