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 SF100-28 EMI filter has been designed to meet MIL-STD-461 specifications.
The SA15-28 is available with 5V triple outputs that are optimal 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 60 grams and is approximately 1.68 cu inch to optimise the Size, Weight and Power (SWaP) of the device. Microchip can also customise the output voltage combinations upon request.
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.
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 offering proven off-the-shelf devices, customers will be able to scale their designs and reduce manufacturing delays. This scalable approach means that customers can 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.
The SA15-28 DC-DC power converter is supported by comprehensive analysis and test reports including worst-case analysis, electrical stress analysis and reliability analysis.
The SA15-28 and SF100-28 external EMI filter are both now available.
