This reference design uses the TPS7H5001-SP pulse-width modulation (PWM) controller and three TPS7H6003-SP half-bridge drivers to contruct a hard-switched full-bridge converter that takes an input ranging from 22V to 36V and generates an isolated 5V output capable of 100W loading. The controller, driver and power FETs are selected to meet geostationary orbit (GEO) class radiation performance. Synchronous rectifiers on the secondary increase efficiency and improve thermal performance compared to conventional diode rectifiers.
