Radiation-tolerant 50W dc-dc converters for space

Microchip Technology has announced a family of radiation-tolerant isolated dc-dc 50W power converters, in nine variants with single and triple-outputs ranging from 3.3V to 28V.

LE50-28 power converters are designed to meet MIL-STD-461. The power converters have a companion EMI filter. This series provides flexibility to parallel up to four power converters to reach 200W.

“The family of devices enable our customers to succeed in new space and LEO environments where components must withstand harsh conditions,” said Leon Gross, vice president of Microchip’s discrete products group.

Radiation tolerance is 50krad total ionising dose and single-event latch-up immunity is 37MeVcm²/mg, said Microchip, adding that test reports are available including worst case analysis, electrical stress analysis and reliability analysis.
