Renesas' rad hard plastic, high-efficiency, monolithic, synchronous buck regulator with integrated MOSFETs offers best-in-class Single Event Transient (SET) performance, which is critical when powering mission critical FPGAs, microcontrollers or microprocessors. The device is an ideal choice to power many of today’s small form factor applications. Radiation hardened plastic package ICs are designed to support multiple mission types, from Low Earth Orbit (LEO) up to Geostationary Earth Orbit (GEO).
