New Rad Hard 17 V Buck Controller with Integrated Gate Drive New Rad Hard 17 V Buck Controller with Integrated Gate Drive â26 Oct 2025 09:17 PM Explore the cosmos like never before with our new radiation hardened buck controller! We're thrilled to introduce the RIC70847 , a revolutionary 17 V buck controller with integrated gate drive. Our new buck controller is a powerhouse of a device that's designed to withstand the harsh conditions of space and keep your systems running smoothly. The Importance of Rad-Hard Components in Space Applications Radiation is a major concern in space applications. Cosmic rays and solar flares can cause irreparable damage to electronic components, leading to system failures and mission-critical errors. That's why radiation hardened (rad hard) components like the RIC70847 are essential for any space-bound application. Our new device has a Total Ionizing Dose (TID) of 100 krad(Si) and no destructive Single Event Effect (SEE) up to Linear Energy Transfer (LET) of 81.8 MeV·cm2/mg. The RIC70847 ensures that your systems remain operational, even in the most extreme environments, with its ability to withstand high levels of radiation. Key Features and Benefits The rad hard buck controller boasts an impressive array of features, including a wide voltage range and optimal load-line regulation, also known as AVP or droop regulation, which improves its transient response. It supports a supply range of 5 V and 12 V nominal, with a load ouput range of 5.25 V to 0.6 V nominal. Featuring a 5 V half bridge gate driver, the RIC70847 is packaged in a hermetically sealed 24-lead flatpack, making it the perfect choice for applications where size and weight are critical. The device operates over the full military ambient temperature range of -55°C to 125°C. Target Applications The device was designed for a number of target applications, including: PoL converters for space grade FPGA, ASIC, and DSP core rails Digital processing payload systems Distributed satellite power systems Paired with peak current mode control, tight reference accuracy, and external FETs, RIC70847 allows for a small and flexible system solution. Infineon IR HiRelâs rad hard R8 power FETs are an ideal logic level transistor to work alongside the buck controller. Conclusion The RIC70847 brings increased reliability and performance to space applications. With its rad hard design, wide voltage range, and high efficiency, the device enables a new world of possibilities for your next space mission! QML-level options are set to be released soon.
