The Texas Instruments TPS7H5001-SP is a radiation-hardness-assured, current mode, dual-output Pulse Width Modulation (PWM) controller for DC-DC converters in space applications.

The device is optimized for both gallium nitride (GaN) and silicon (Si) semiconductor systems and features a high switching frequency combined with low current consumption.

The device has also been designed with a small physical footprint and is packaged in a 22-pin ceramic dual flat package.

The TPS7H5001-SP PWM is highly suited to fully exploiting the high-efficiency benefits and area reduction of GaN based DC-DC converters.

It features integrated dead-time programmability and synchronous rectifier control outputs that enable the targeting of high-efficiency and high-performance topologies. In addition, the TPS7H5001-SP is able to supports single-ended converter topologies through the user-defined control of the maximum operating duty cycle, adding additional versatility.

The TPS7H5001-SP can be driven with an external clock using the internal oscillator at a user-defined frequency or through the SYNC pin.

The internal reference, which is accurate to 0.613 V ±1%, allows for the design of high-current buck converters for FPGA core voltages.

Additional programmable features include soft start functionality, the UVLO threshold, and slope compensation.
