    Summary points:

    • The SA15-28 15-Watt DC-DC power converter offers radiation tolerance to 100 kilorads, and is built for harsh space environments.
    • Weighing 60 grams and measuring 1.68 cubic inches, the SA15-28 supports 5-volt triple outputs and customizable voltage combinations.
    • The companion SF100-28 EMI filter supports as much as 100 Watts of output and is compatible with Microchip's SA50 power converters and SF200 filter for system flexibility.

    CHANDLER, Ariz. – Microchip Technology Inc. in Chandler, Ariz., is introducing the SA15-28 off-the-shelf radiation-hardened DC-DC 15-Watt power converter with a companion SF100-28 EMI filter for space applications.

    The SA15-28 is available with 5-volt triple outputs for use with point-of-load converters and low-dropout linear regulators to power FPGAs and microprocessors. The small-form-factor SA15-28 weighs 60 grams and measures 1.68 cubic inches. Microchip can customize the output voltage combinations upon request.

    The SF100-28 EMI noise suppression filter can be used with other power converters with a total output power of as much as 100 Watts. For added flexibility in space applications, the SA15-28 and SF100-28 are compatible with Microchip's existing SA50 series of power converters and SF200 filter.

    Radiation tolerance

    SA15-28 DC-DC converters are designed to operate in temperatures from -55 to 125 degrees Celsius, and offers radiation tolerance to 100 kilorads total-dose.

    The SA15-28 DC-DC power converter comes with analysis and test reports including worst-case analysis, electrical stress analysis and reliability analysis.
