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 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 an integrated synchronous rectifier control outputs and dead-time programmability in order to target high efficiency and high-performance topologies.
The TPS7H500x-SEP series can be driven using an external clock through the SYNC pin or by using the internal oscillator at a frequency programmed by the user. The controller family offers the user various 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.
