Microchip Technology has announced a new family of Radiation-Tolerant (RT) LE50-28 isolated DC-DC 50-W power converters available in nine variants with single- and triple-outputs ranging from 3.3 V to 28 V.

These power converters meet the increasing demand for standard space grade products that are reliable, cost effective and configurable — driven by the rapidly growing Low-Earth-Orbit (LEO) market as private and public entities alike explore the new space region for everything from 5G communication and cube satellites to IoT applications.

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 customize 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. Designers can use these high-reliability radiation-tolerant power devices 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 Ionizing Dosis (TID) and Single Event Effects (SEE) latch-up immunity of 37 MeV·cm2/mg linear energy transfer.

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.

The new family of LE50-28 devices are supported by comprehensive analysis and test reports including worst case analysis, electrical stress analysis and reliability analysis.

The LE50-28 single-output and LE50-28 triple-output are now available.
