This space-grade power device is a standard, non-hybrid DC-DC isolated power converter with a companion electromagnetic interference (EMI) filter that operates from a 28V satellite bus in harsh environments.
The SA15-28 is available with 5V triple outputs that are ideal for use with point-of-load converters and low-dropout linear regulators to power FPGAs and microprocessors (MPUs). The small-form-factor SA15-28 weighs 60gand is approximately 1.68 cu inch to optimise the Size, Weight and Power (SWaP) of the device. Microchip can customise the output voltage combinations upon request.
“Microchip’s space-grade portfolio with the new SA15-28 power converter and SF100-28 EMI filter allows our customers to customise 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.”
The SF100-28 EMI noise suppression filter can be used with numerous power converters with a total output power of up to 100W. For added flexibility in space applications, the SA15-28 and SF100-28 are fully compatible with Microchip’s existing SA50 series of power converters and SF200 filter.
High reliability and performance are essential for power management solutions operating in harsh environments. The SA15-28 DC-DC power converter is designed to operate across a wide temperature range, from −55°C to +125°C, and offers radiation tolerance up to 100 krad TID.
By providing proven off-the-shelf devices, Microchip enables customers to confidently scale their designs and reduce manufacturing delays. This scalable approach enables customers to upgrade from Commercial-Off-The-Shelf (COTS) to space-qualified level or from Radiation-Hardened By Design (RHBD) to sub-QML packaging options in ceramic or plastic.
