The LEO market is rapidly growing as private and public entities alike explore the new space region for everything from 5G communication and cube satellites to IoT applications. There is an increased demand for standard space grade solutions that are reliable, cost-effective, and configurable. To meet this market need, Microchip Technology has announced a new family of RT LE50-28 isolated DC-DC 50W power converters offered in nine variants with single- and triple-outputs ranging from 3.3V to 28V.
The off-the-shelf family of power converters are created to meet MIL-STD-461. The power converters have a companion EMI filter and supply customers ease of design to scale and customise by selecting one or three outputs based on the voltage range required for the end application. This series provides flexibility to parallel up to four power converters to reach 200W.
Designed to serve 28V bus systems, the converters can be integrated with the company's PolarFire FPGAs, microcontrollers and LX7720-RT motor control sensor for a complete electrical system solution. Designers can employ these high-reliability radiation-tolerant power solutions to greatly lessen 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 power converters provide various electrical connection and mounting options. The LE50 series is manufactured with traditional surface mount and thru-hole components on a printed wiring board. This distinction in the manufacturing process can lessen time to market and risks associated with supply chain disruptions.
The family supplies space-grade radiation tolerance with 50 Krad TID and SEE latch-up immunity of 37MeV·cm2/mg linear energy transfer.
The company provides a wide range of components to support the new space evolution, using a sub-QML strategy to bridge the gap between traditional QML components and 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, which permits lower screening requirements for lower cost and shorter lead times.
The company's extensive space solutions include FPGAs, power and discrete devices, memory products, communication interfaces, oscillators, MPUs and MCUs, supplying a wide range of options across qualification levels, and the largest qualified plastic portfolio for space applications.
