The off-the-shelf LE50-28 family of 50 W DC-DC power converters from Microchip are designed to meet MIL-STD-461.
The power converters have a companion EMI filter, and offer customers ease of design to scale and customise by choosing one or three outputs based on the voltage range needed for the end application. This series provides flexibility to parallel up to four power converters to reach 200 W.
Designed to serve 28 V bus systems, the LE50-28 isolated DC-DC power converters can be integrated with Microchip’s PolarFire FPGAs, microcontrollers and LX7720-RT motor control sensor for a complete electrical system solution. Designers can use these high-reliability radiation-tolerant power solutions to significantly reduce system-level development time.
“The new family of LE50-28 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. “Our off-the-shelf products offer a reliable and cost-effective solution designed for the durability our customers have come to expect from Microchip.”
The LE50-28 power converters offer a variety of electrical connection and mounting options. The LE50 series is manufactured with conventional surface mount and thru-hole components on a printed wiring board. This distinction in the manufacturing process can reduce time to market and risks associated with supply chain disruptions.
Microchip offers a wide range of components to support the new space evolution with sub-QML strategy to bridge the gap between traditional Qualified Manufacturers List (QML) components and Commercial-Off-The-Shelf (COTS) components. Designed for new space applications, sub-QML components are the optimal solution that combines the radiation tolerance of QML components with our space flight heritage that permits lower screening requirements for lower cost and shorter lead times.
