Radiation-tolerant DC-DC converters for power electronics space applications introduced by Microchip
CHANDLER, Ariz. – Microchip Technology Inc. in Chandler, Ariz., is introducing the LE50-28 radiation-tolerant isolated 50-Watt power DC-DC converters for low-Earth-orbit space applications.
These power electronics devices are available in nine variants with single- and triple-outputs ranging from 3.3 to 28 volts.
The off-the-shelf LE50-28 power converters meet MIL-STD-461, and have a companion EMI filter to enable systems designers to scale and customize by choosing one or three outputs based on the voltage range needed. This series can parallel as many as four power converters to reach 200 Watts.
Designed to serve 28-volt bus systems, the LE50-28 isolated DC-DC power converters can integrate with the Microchip PolarFire FPGAs, microcontrollers, and LX7720-RT motor control sensor. Designers can use these high-reliability radiation-tolerant power solutions to reduce system-level development time.
The LE50-28 power converters offer electrical connection and mounting options, and come with conventional surface-mount and through-hole components on a printed wiring board.
The LE50-28 family offers space-grade radiation tolerance with 50 Krad total ionizing dose and single event effects (SEE) latch-up immunity of 37 MeV·cm2/mg linear energy transfer. For more information contact Microchip online at www.microchip.com.
