MB SERIES

15W, low noise, triple output radiation hardened DC-DC power converter for Space applications

Pending

Benefits

Accommodates most major power buses, 28V, 50V, 70V, and 100V

Integrated input filter to ensure EMC/EMI compatibility to most satellite power buses

No limitation on number of outputs though most requirements are triple output configuration

Each output can be configured to meet output voltage levels up to 15V and any current level up to 1A

Guaranteed voltage accuracy and regulation to within 1% begin-of-life (BOL) and 2% end-of-life (EOL) accounting for temperature, radiation and aging effects

No cross regulation and cross talk as each output is independently regulated

Two design patents are deployed to maximize efficiency performance

Efficiency is in the range of 65 to 75% depending on output voltage, current and power.

Each output uses linear regulator enabling output noise to be less than 1 mVRMS

Conducted susceptibility (CS) rejection is as high as 100 dB as a result of a two stage regulation design

Outputs are orderly sequenced during power-up and power-down to ensure proper biasing for RF amplifier devices

Isolated ON/OFF tele-command and ON/OFF status telemetry with a latching relay

Two established assembly outlines for differing output powers

All components are space flight qualified to class S
