Radiation-Tolerant DC-DC 50-Watt Power Converters Provide High-Reliability Solution for New Space Applications
May 07 2024 - 9:10AM
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
(Nasdaq: MCHP)
today announces 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 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.
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 Ionizing Dose (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. 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.
Microchip’s 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. For

Support and Resources
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.
Pricing and Availability
The LE50-28 single-output and LE50-28
triple-output are now available. For additional information and to
