The PWM controller is suitable for use in space satellite point of load supply for FPGAs, microcontrollers, data converters, and ASICs.
The TPS7H5005-SEP is a radiation-tolerant, 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 TPS7H5005-SEP can be configured from 100 kHz to 2 MHz while still maintaining very low current consumption, making it ideal for taking full advantage of reduced area and high-efficiency devices. benefits of GaN-based DC-DC converters. The device has an integrated synchronous rectifier control outputs and dead-time programmability to target high-efficiency and high-performance topologies.
The TPS7H500x-SEP series can be driven with an external clock via the SYNC pin or by using an internal oscillator at a user-programmed frequency. The controller family offers the user a variety of options for switching outputs, synchronous rectification capability, dead time (fixed or configurable), leading edge blank time (fixed or configurable), and duty cycle limit. Each device in the TPS7H500x-SEP series has a 24-pin TSSOP package. The PWM controller is suitable for use in space satellite point of load supply for FPGAs, microcontrollers, data converters, and ASICs.
