Microchip expands space power portfolio with radiation-tolerant GaN converter. October 15, 2026 Microchip Technology, announces the POL-05-20S-T, a radiation-tolerant, Point-of-Load (POL) converter, designed to address the demanding power requirements of space processing applications. The new device uses Gallium Nitride (GaN) power devices to deliver up to 20A of output current with high efficiency and power density. The converter is supplied in a compact, 25g surface-mount package measuring 1.51" x 1.51" x 0.45". By delivering 20A in this footprint, the device helps engineers manage the size, power and energy constraints that accompany increasingly capable onboard processing systems. The GaN-based design is intended to provide a combination of high efficiency, high power density and continuous current capability for challenging space power applications. "Space designers are integrating increasingly powerful digital processing, creating demand for compact power solutions that can respond quickly, while operating reliably in harsh environments," said Ronan Dillon, senior director of Microchip's high-reliability and RF business unit. "The POL-05-20S-T extends our space power portfolio with a high-current GaN solution that helps customers achieve high power density, design flexibility and system-level reliability." The POL-05-20S-T is designed for high-current, fast-transient applications such as for the core voltage rails of FPGAs, microcontrollers, ASICs and other processing-intensive digital loads. It combines a synchronous buck topology with current-mode control to support fast current transients and stable operation. With a wide input range of 4.75V to 13.2V and adjustable 0.7V to 5V output, the device offers flexibility to address multiple power rails and system architectures. Designed for harsh radiation environments, the POL-05-20S-T has electrical parameters specified before and after irradiation up to a Total Ionizing Dose (TID) of 50 krad. The device is characterized for Single Event Effects (SEE) up to a Linear Energy Transfer (LET) of 43 MeV·cm[2]/mg. It operates from −55°C to +100°C at full load, supporting systems exposed to wide temperature variations over the course of a mission. To support reliable power delivery, the POL-05-20S-T incorporates remote sensing, undervoltage and overvoltage protection, soft start, an enable pin and power-good indication pin. Adjustable output voltage, a wide input range and output droop regulation further help designers tailor the converter to high-current loads requiring tight voltage regulation and rapid transient response. Microchip delivers a comprehensive space power suite that is part of an end-to-end solution for space system designers, including EMI filters, DC-DC converters, point-of-load regulators, Hi-Rel discrete components, FPGAs and the PIC64-HPSC High-Performance Spaceflight Computing devices. Built on decades of space heritage, the portfolio helps customers simplify development, reduce design risk and accelerate deployment of mission-critical space systems.

Microchip launches radiation-tolerant 20 A GaN converter for space. Microchip Technology has expanded its space power portfolio with the POL-05-20S-T, a radiation-tolerant gallium nitride (GaN) point-of-load (POL) converter designed for high-current processing applications. The device delivers up to 20 A of continuous output current in a compact surface-mount package, targeting both new-space and traditional space systems. Measuring 1.51 x 1.51 x 0.45 inches and weighing 25 g, the converter is designed to meet the power, size and energy constraints of increasingly capable onboard processing systems. Its GaN-based power stage is intended to combine high efficiency and power density with the current capability required by demanding space applications. "Space designers are integrating increasingly powerful digital processing, creating demand for compact power solutions that can respond quickly, while operating reliably in harsh environments," said Ronan Dillon, senior director of Microchip's high-reliability and RF business unit. "The POL-05-20S-T extends our space power portfolio with a high-current GaN solution that helps customers achieve high power density, design flexibility and system-level reliability." Designed for high-current digital loads The POL-05-20S-T is intended for high-current, fast-transient applications, including core power rails for FPGAs, microcontrollers, application-specific integrated circuits (ASICs) and other processing-intensive digital devices. It combines a synchronous buck converter topology with current-mode control to support rapid load-current changes and stable operation. The device accepts an input voltage of 4.75 V to 13.2 V and provides an adjustable output from 0.7 V to 5 V, allowing it to support a range of power rails and system architectures. Features intended to support power delivery and system integration include remote sensing, undervoltage and overvoltage protection, soft start, an enable input and a power-good indication output. Adjustable output voltage and droop regulation provide further flexibility for high-current loads requiring tight voltage regulation and rapid transient response. Radiation tolerance for space environments Designed for operation in radiation environments, the POL-05-20S-T has electrical parameters specified before and after irradiation to a total ionising dose (TID) of 50 krad. It has also been characterised for single-event effects (SEE) at a linear energy transfer (LET) of up to 43 MeV·cm[2]/mg. The converter operates across a temperature range of −55°C to +100°C at full load, supporting space systems exposed to wide temperature variations during a mission. Part of Microchip's space power portfolio The POL-05-20S-T joins Microchip's broader portfolio of components and subsystems for space applications.
