Global semiconductor company Microchip Technology has accelerated the expansion of its power portfolio for space applications.

Microchip announced on the 27th that it has released a new radiation-hardened 15W DC-DC power converter, the 'SA15-28', and a compatible EMI filter, the 'SF100-28'.

With this new product, Microchip provides a power management solution that meets the requirements of reliability, performance, and flexibility in the harsh space environment.

In particular, the SA15-28 DC-DC converter is a high-durability product that complies with MIL-STD-461 standards and has a temperature range of -55°C to +125°C and radiation resistance of up to 100 krad.

It is compatible with existing systems using 28V satellite buses, enabling a stable power supply for complex space missions.

Based on a compact and lightweight design, the SA15-28 is designed to weigh 60g and have a volume of approximately 1.68 cubic inches, meeting SWaP (Size, Weight and Power) requirements.

It supports a triple output structure (including 5V) optimized for FPGAs and microprocessors (MPUs), and can be customized for various output combinations.

Leon Gross, vice president of Microchip, said:“This product maximizes flexibility and accelerates product development with a COTS-based, non-hybrid discrete design,” the company said. “We will support our space customers to quickly implement solutions tailored to their project requirements.”

The included SF100-28 EMI filter supports up to 100W output power and is also compatible with existing SA50 series and SF200 filters.

This allows customers to take a modular approach to designing diverse systems and improve development efficiency through integrated operation with existing product lines.

Microchip also provides a variety of development support tools to help power system designers perform design verification based on professional test reports, including reliability analysis and electrical stress evaluation, using the SA15-28 power converter.

Products are available now through authorized global distributors and Microchip authorized channels, with scalable packaging options available from COTS to space-qualified grade.
