Renesas' rad tolerant, 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 tolerant plastic-package ICs are designed to support the emerging field of small satellites (smallsats) that will provide solutions such as high-speed internet connections to hundreds of millions of users in communities, governments and businesses worldwide.
