TTM Technologies, Inc. announced the release of the MSK5065RH module, a high-efficiency, radiation-hardened switching regulator optimized for demanding space and defense environments. As part of TTM's expanding space-grade microelectronics portfolio, the MSK5065RH modules delivers robust performance, exceptional radiation tolerance, and a compact footprint ideal for next-generation satellite and spacecraft systems. The MSK5065RH module is a radiation-hardened, synchronous buck regulator capable of supplying over 3 amperes of continuous output current, with peak efficiencies exceeding 90%. Designed for radiation-sensitive environments, it has been tested to withstand up to 100 krad (Si) Total Ionizing Dose ("TID").

It offers low sensitivity to Single Event Effects ("SEE"), making it a reliable choice for low-earth-orbit ("LEO), medium-earth-orbit ("MEO"), and deep space missions. The MSK5065 RH module is based on the ISL73007SEH from Renesas Electronic Corporation, a trusted radiation-hardened regulator known for its reliability in harsh environments. The MSK5065HR module is ideal for power distribution networks, FPGA/processor core supplies, and high-reliability systems requiring fault-tolerant power management.

The MSK5065Rh module is now available in flight-proven Class K and Class H screening levels. Engineering models are also available for evaluation and prototyping. For detailed specifications, download the MSK5065RH dataset and Application Note.
