Microchip unveils new radiation-tolerant power converters for space applications
The Low-Earth Orbit (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 Radiation-Tolerant (RT) LE50-28 isolated DC-DC 50W power converters available in nine variants with single- and triple-outputs ranging from 3.3V to 28V.
The off-the-shelf LE50-28 family of power converters 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 200W.
Designed to serve 28V 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.
The LE50-28 family offers space-grade radiation tolerance with 50 Krad Total Ionising Dosis (TID) and Single Event Effects (SEE) latch-up immunity of 37 MeV·cm2/mg linear energy transfer.
