描述

The TPS7H5001-SP is a radiation-hardness-assured, current mode, dual output PWM controller optimized for both silicon (Si) and gallium nitride (GaN) power semiconductor based DC-DC converters in space applications. The high switching frequency capability of the TPS7H5001-SP, small footprint, and low-current consumption makes it ideal for fully exploiting the area reduction and high-efficiency benefits of GaN based DC-DC converters. The TPS7H5001-SP features integrated synchronous rectifier control outputs and dead-time programmability in order to target high-efficiency and high-performance topologies. In addition, the TPS7H5001-SP supports single-ended converter topologies by providing the user flexibility to control the maximum duty cycle. The 0.613 V ±1%-accurate internal reference allows design of high-current buck converters for FPGA core voltages.

The TPS7H5001-SP can be driven using an external clock through the SYNC pin or by using the internal oscillator at a frequency programmed by the user. Other programmable features include the UVLO threshold, soft start, and slope compensation. The TPS7H5001-SP is packaged in a small 22-pin ceramic dual flat package.
