Satellites and subsystems > Electrical and electronic equipment (EEE) > TPS7H5001-SP - Radiation-hardened QMLV, 2-MHz, dual-output PWM controller with synchronous rectification
Key highlights
The Texas Instruments TPS7H5001-SP is a radiation-hardened PWM controller designed for space applications.
It provides a number of features that are beneficial for the design of DC-DC converter topologies intended for space applications.
The controller can be driven using an external clock through the SYNC pin or by using the internal oscillator at a frequency programmed by the user. It also 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. It has a 22-pin CFP package.
Applications
- Space satellite point of load supply for FPGAs, microcontrollers, data converters, and ASICs
- Communications payload
