LE50-28-3R3-12T数据手册Microchip中文资料规格书

描述 Description

The LE50-28 is an Isolated DC-to-DC converter capable of delivering up to 50W of output power in a small size design. The LE family provides a radiation Tolerant solution with excellent TID and SEE performance focusing  New Space and LEO (Low Earth Orbit) applications. With forward converter topology and a patented magnetic feedback, the LE50-28 is optimized for applications where isolated DC voltage conversion is required. The discrete surface mount design facilitates customization with reasonable lead time and modest NRE cost.To achieve MIL-STD-461 EMI compliance, an external filter is required. Off the shelf filters such as Microchip’s SF200-28-28S are available.As a non-hybrid space grade DC-DC power converter module in the market, the LE50-28 series excels in its robustness in the New Space applications with 1.00 x106 hours of MTBF. The LE50-28 is available in 3.055” x 2.055” x 0.5” package.
