There is an increased demand for standard space grade solutions that are reliable, cost effective and configurable. To meet this market need, Microchip Technology announces a new family of <a href=\"https:\/\/www.microchip.com\/en-us\/products\/power-management\/dc-dc-switching-converters-and-controllers\/dc-dc-switching-converters-and-regulators\/radiation-tolerant-isolated-dc-dc-converters?utm_source=pressrelease&amp;utm_medium=pressrelease&amp;utm_campaign=le50&amp;utm_bu=dpg\"><strong>Radiation-Tolerant (RT) LE50-28 isolated DC-DC 50W power converters<\/strong><\/a> available in nine variants with single- and triple-outputs ranging from 3.3V to 28V.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">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-Watts. &nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Designed to serve 28V bus systems, the LE50-28 isolated DC-DC power converters can be integrated with Microchip\u2019s 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.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">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.&nbsp; &nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">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\u00b7cm2\/mg linear energy transfer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">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.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Microchip\u2019s extensive space solutions include FPGAs, power and discrete devices, memory products, communication interfaces, oscillators, microprocessors (MPUs) and MCUs, offering a broad range of options across qualification levels, and the largest qualified plastic portfolio for space applications.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">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.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
