Rad Hard Power
Renesas' radiation hardened (rad hard) power products achieve the stringent voltage accuracy required of FPGAs, ASICs, microprocessors, and microcontrollers used in space and harsh environment applications. Our solutions enable regulation accuracy over input voltage, load current variation, switching noise, and large load transients and have proven highly reliable within mixed radiation exposure rates and other harsh environment variants.
Renesas has an unparalleled track record of providing highly reliable, efficient and accurate radiation hardened power products that achieve the stringent voltage accuracy required for harsh environments.
The low dose rate ionizing dose response of semiconductors has become a key issue in space applications. Renesas is addressing this market by wafer-by-wafer low dose rate acceptance testing as a complement to current high dose rate acceptance testing.
Renesas is one of only a few RHA Defense Logistics Agency (Land and Maritime) QML suppliers. All of Renesas' radiation hardened SMD products are MIL-PRF-38535/QML compliant and are 100% burned in.
Radiation Hardened Single-Chip Synchronous Buck and LDO
The rad hard ISL70005SEH is the only point-of-load (POL) power solution that reduces size, weight and power (SWaP) by integrating a synchronous buck and low dropout (LDO) regulator in one monolithic IC.
Radiation Hardened Driver Circuit with Integrated Decoder
The ISL72814SEH rad hard 16-channel current driver with integrated decoder for satellite applications reduces command and telemetry solution size by 50%.
Radiation Hardened 100V & 200V GaN FET Power Supply Solutions
The ISL70040SEH low-side GaN FET driver and ISL7002xSEH GaN FETs enable primary and secondary DC/DC converter power supplies in launch vehicles and satellites, downhole drilling and high reliability industrial applications.
Radiation-Hardened Quad Power Supply Sequencers
The ISL70321SEH and ISL73321SEH quad power supply sequencers are designed to drive point-of load (POL) regulators that power high-performance FPGAs and complex, multi-rail power systems.
