The LE50-28-12S-A-T from Microchip Technology is a Radiation-Hardened Buck DC-DC Converter that converts an input voltage of 22 - 38 V to an output voltage of 12 V. It delivers an output power of up to 50 W and has an efficiency of 80% (full-load). This isolated converter provides a radiation-tolerant option with top-class total ionizing dose (TID) and single-event effects (SEE) performance for space and military applications. It has a forward converter topology and patented magnetic feedback, optimizing the system for applications where isolated DC voltage conversion is required. This converter is supported by a discrete surface-mount design that facilitates customization with reasonable lead time and modest NRE cost. It requires an external filter to be used to suppress undesirable interfering signals and achieve MIL-STD-461 EMI compliance. This buck converter is available in a surface-mount package that measures 3.055 x 2.055 x 0.500 inches.
