TIDT250A March 2021 – May 2022
This reference design uses a single UCC25800-Q1 to drive two LLC transformers. Each isolated output feeds into a TPS7A39 dual-channel positive and negative output LDO. PMP23124 can be used to bias two wide band gap FETs that require a positive and negative voltage to drive. Each output can be loaded to 2.8 W.
