마이크로칩테크놀로지(아시아 총괄 및 한국대표 한병돈)가 새로운 내방사선(RT) LE50-28 절연 DC-DC 50W 파워 컨버터 제품군을 출시했다.
Implementing high-reliability solutions for new space industry applications
The new product, a new radiation-resistant power converter for high-reliability solutions for emerging space industry applications, is expected to enable the development of a variety of products ranging from 5G communications and cube satellites to IoT applications.
Microchip Technology Inc. (NASDAQ: MCHP) today announced the availability of its new radiation-hardened LE50-28 isolated DC-DC 50W power converter family.
The newly launched product family comes in nine options with single and triple outputs ranging from 3.3V to 28V.
The LE50-28 power converter family is designed to be off-the-shelf and compliant with MIL-STD-461. The power converters include a companion EMI filter and are available with a choice of single or triple outputs depending on the voltage range required by the end application, allowing for easy expansion and customization. The family also offers the flexibility to connect up to four power converters in parallel to reach 200W.
The LE50-28 isolated DC-DC 50 W power converter is designed to support 28 V bus systems and can be integrated with Microchip’s PolarFire® FPGA, microcontroller and LX7720-RT motor control sensor to create a complete electrical system solution. Developers can significantly reduce system-level development time with these high-reliability, radiation-hardened power solutions.
“The new LE50-28 family of devices provides customers with a solution that is ready for the new space and LEO environments where components must withstand the harsh conditions,” said Leon Gross, vice president of Microchip’s Discrete Products business unit. “Microchip’s off-the-shelf products provide customers with a robust, reliable and cost-effective solution.”
The LE50-28 power converter offers a variety of electrical connection and mounting options. The LE50 series is manufactured with conventional surface-mount and thru-hole components on printed wiring boards, a manufacturing process that reduces time to market and the risks associated with supply chain disruption.
The LE50-28 family provides space-grade radiation tolerance with a total ionizing dose (TID) of 50 kilorads (Krad) and single event effects (SEE) latch-up tolerance of 37 MeV-cm2/mg linear energy transfer (LET).
Microchip offers a range of components based on its “sub-QML strategy,” which bridges the gap between existing Qualified Manufacturers List (QML) components and commercial-off-the-shelf (COTS) products to support the development of the evolving new space industry. Designed for new space applications, sub-QML parts are developed based on our experience developing existing space products, so they have the same radiation tolerance as QML parts, but can be developed at a reduced level of screening (inspection procedures) to reduce development costs and development time.
Microchip offers a wide range of space solutions including FPGAs, power and discrete devices, memory products, communication interfaces, oscillators, microprocessors (MPUs) and MCUs, with various qualification levels and options, and offers the broadest portfolio of qualified plastics for space applications.
