Keywords: digital isolators  synchronous rectifiers  controlling synchronous MOSFETs 

[Summary of tips] Many of today's switching power supplies implement synchronous rectifiers to improve efficiency. In isolated topologies, the power-supply controller typically is located on the primary side of the isolation barrier, while the synchronous rectifiers are located on the secondary side. The control signals must bridge the isolation......
