Continue reading to learn what makes Infineon HiRel’s latest IC standout in high reliability applications. Key features The RIC70847 is Infineon’s first-in-family radiation hardened buck controller with integrated gate drive. It operates with a 5 V drive, optimized to work seamlessly with logic level FETs, such as our radiation hardened R8 MOSFETs. Key product features include: Total Ionizing Dose (TID) of 100 krad(Si) Single Event Effect (SEE): SEL, SEB, SEGR free and SET characterized up to 81.9 MeV·cm2/mg Abs max input voltage of 17.1 V supports 5 V and 12 V inputs Supports output voltage down to 0.6 V 0.6 V ±1% feedback voltage (reference + error amplifier offset) Programmable fixed frequency from 100 kHz to 2 MHz Integrated 5 V half-bridge gate driver RIC70847’s wide voltage range supports multiple system architectures and its tight reference voltage accuracy is compatible with the latest FPGAs. Load line regulation A key benefit of the RIC70847 is its advanced load-line regulation (LLR). In high reliability applications, even slight variations in voltage can have significant consequences. By providing a more stable voltage output, the RIC70847 helps ensure that systems operate reliably and efficiently. The device's ability to maintain a stable output voltage, despite changes in load conditions, is a critical factor in its suitability for mission-critical operations. Overall, the device’s optimized LLR helps reduce output capacitor size, saving space and weight in your designs. Additional benefits include: Increased efficiency under heavy loads, thanks to lower voltage demands Improved dynamic performance, with fewer output capacitors required to maintain a stable voltage Simplified control and compensation, as the outer loop zero removes the LC filter's double pole from the equation Inherent current sharing in multi-phase systems, which promotes a more balanced and efficient distribution of power Applications The RIC70847 is an attractive choice for designers seeking to improve the performance and reliability of their overall power systems, particularly for modern FPGAs with demanding core rail power requirements. Its design addresses the limitations of existing solutions, which often fall behind in performance and footprint as power needs escalate. By meeting high power needs while maintaining an efficient footprint, enabled by its robust LLR feature and use of an external FET, the RIC70847 offers a versatile and reliable component for a variety of power management applications, including the latest FPGA designs with optimized drive voltage, making it a valuable addition to any power management system. Potential application for this device includes: Point-of-load (PoL) converter for space grade FPGA, ASIC, and DSP core rails Digital processing payload systems Distributed satellite power systems Learn more The RIC70847’s small form factor and heightened efficiency bring top SWaP (Size, Weight and Power) advantages to next-gen space missions.
