10.1 Application Information

The TPS7H500x-SP series is a family of radiation-hardness-assured current mode PWM controllers that can be utilized for designing space-grade DC-DC converters. Each device should be paired with external gate drivers in order to provide control of the power semiconductor device(s) of the converter power stage. By allowing for switching frequencies up to 2 MHz, the controllers provide many advantages for GaN power semiconductor based designs. The TPS7H500x-SP family can be used for the design of a number of common DC-DC converter topologies, including but not limited to: buck, flyback, forward, active-clamp forward, push-pull, and full-bridge.
