International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
The convertors can be configured to meet a range of spacecraft power bus voltages, varying output load requirements and telemetry needs and are optimised to ensure maximum performance for sensitive RF equipment onboard spacecraft, such as receivers, transmitters, beacons, low noise amplifiers (LNAs) and up/down convertors.
This platform-based approach to satellite space power designs provides all of the benefits of a high-volume standard product while offering the customisation necessary for satellite power requirements.
The overall cost and design effort for satellite manufacturers is reduced by simplifying custom power convertor development.
IR's Mx series offers two power levels.
The MA platform is rated at 5W and the MB platform is rated at 15W output power.
The platform has three outputs; each output can be configured from 3.3 to 15V and independently regulated to eliminate cross talk and minimise noise.
Output noise is less than 1mV RMS and conducted susceptibility (CS) rejection is better than 95dB.
In addition to very low input/output noise characteristics and world class CS rejection performance, the design platform offers guaranteed output voltage accuracy and end-of-life output voltage variations of less than 2%.
The Mx series can accommodate common satellite power buses from 20 to 100V.
An input filter is included to meet stringent EMI requirements.
An isolated telemetry tele-command (TC) interface and output turn-on/turn-off sequencing (normally required by RF amplifiers) capability are also offered.
