15W DC-DC konverter til rumapplikationer

Microchip Technology lancerer SA15-28, der er en 'off-the-shelf' 15W DC-DC 15W med tilhørende SF100-28 EMI filter, der er designet til at honorere MIL-STD-461 specifikationerne (in english).

Traditional space applications have long required space-grade components to help ensure the success of missions. With over 60 years of space heritage, Microchip Technology continues to broaden its space portfolio and today announces 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 optimize the Size, Weight and Power (SWaP) of the device. Microchip can customize 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 customize and scale their space power systems to meet the specifications of their application. The non-hybrid or discrete component-based construction is specifically designed to enable flexibility and faster time to market, says said Leon Gross, corporate vice president of Microchip’s high-reliability and RF business unit. 

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.

By offering 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.
