Description

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