Microchip Technology has expanded its space portfolio with the introduction of the SA15-28, a radiation-hardened 15W DC-DC power converter, and its companion SF100-28 EMI filter. These off-the-shelf components are designed to meet the rigorous demands of space applications, ensuring reliable power management in harsh environments.
Microchip unveils SA15-28 15W DC-DC power converter for space.
Includes SF100-28 EMI filter meeting MIL-STD-461 specifications.
Radiation-hardened, operates from -55°C to +125°C with 100 krad TID.
Optimized for FPGAs and microprocessors with 5V triple outputs.
Small form factor (60 grams, 1.68 cu inch) for SWaP efficiency.
Scalable with COTS to sub-QML packaging options.
The SA15-28 DC-DC power converter is a non-hybrid, radiation-hardened device designed for a 28V satellite bus. With a weight of 60 grams and a compact size of 1.68 cubic inches, it optimizes Size, Weight, and Power (SWaP) for space missions. The converter provides 5V triple outputs, making it ideal for powering FPGAs and microprocessors alongside point-of-load converters and low-dropout linear regulators. Microchip offers customizable output voltage combinations to meet specific application needs.
The SF100-28 EMI filter, designed to meet MIL-STD-461 specifications, supports power converters with up to 100W output. It ensures electromagnetic compatibility, reducing noise in sensitive space systems. The filter is fully compatible with Microchip’s existing SA50 series power converters and SF200 filter, offering flexibility for integration into various space applications.
Microchip’s SA15-28 and SF100-28 enable scalable power management solutions, allowing customers to transition from Commercial-Off-The-Shelf (COTS) to space-qualified or Radiation-Hardened By Design (RHBD) to sub-QML packaging in ceramic or plastic. “Microchip’s space-grade portfolio with the new SA15-28 power converter and SF100-28 EMI filter allows our customers to customize and scale their space power systems to meet the specifications of their application,” said Leon Gross, corporate vice president of Microchip’s high-reliability and RF business unit. “The non-hybrid or discrete component-based construction is specifically designed to enable flexibility and faster time to market.”
Designed to operate in extreme conditions, the SA15-28 functions reliably across a temperature range of -55°C to +125°C and offers radiation tolerance up to 100 krad Total Ionizing Dose (TID). Supported by comprehensive analysis, including worst-case, electrical stress, and reliability reports, these components ensure high performance and durability for space missions.
This launch strengthens Microchip’s 60-year legacy in space technology, providing reliable, scalable solutions for power management. The SA15-28 and SF100-28 empower customers to accelerate development and deployment while maintaining mission-critical reliability in space applications.
