SLVSF07 July 2021 TPS7H5001-SP
The TPS7H5001-SP is a radiation-hardness-assured, current mode, dual output PWM controller optimized for silicon (Si) and gallium nitride (GaN) based DC-DC converters in space applications. The switching frequency of the TPS7H5001-SP can be configured from 100 kHz to 2 MHz while still maintaining a very low current consumption, which makes it ideal for fully exploiting the area reduction and high efficiency benefits of GaN based DC-DC converters. The device 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.
