Microchip expands its space portfolio with 15W DC-DC power converter
Microchip has announced the SA15-28 off-the-shelf radiation-hardened DC-DC 15W power converter with a companion SF100-28 EMI filter that are designed to meet MIL-STD-461 specifications. 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 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 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.
High reliability and performance are critical 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.
Development Tools
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.
