Selection and Analysis of COTS power management devices under radiation

This paper presents a survey of a number of commercial devices that have been tested for radiation, both Total Ionizing Dose and Single Event Effects. The results presented here will show that choosing power management devices that are intended to operate in a high radiation environment can be challenging. Renesas will also outline how it can serve the power management market with lower cost, radiation characterized devices that are ideal for New Space applications. These devices bridge the challenges of providing higher reliability and radiation assurance, while still being sensitive to the costs of small satellites and large constellations.
