Abstract
A radiation tolerant gate driver for power converters with active-clamp reset and active-driven synchronous rectification uses integrated logic drivers for high efficiency and wide input range. A keep alive circuit prevents power train transistors from remaining on for extended durations after a transient or an undervoltage lockout (UVLO) event. Each of the integrated logic drivers includes two gate driver circuits, where one of the gate driver circuits uses the output of the other of the gate driver circuits as input per a logic table of the integrated logic driver, to ensure no shoot-through when the respective power train transistors are turned on and off.
