The LMR51635 is a wide-VIN, easy-to-use, synchronous buck converter capable of driving up to 3.5A load current. With a wide input range of 4.3V to 60V, the device is designed for a wide range of industrial applications for power conditioning from an unregulated source.

The LMR51635 operates at 400kHz switching frequency to support use of relatively small inductors for an optimized design size. The device has pulse frequency modulation (PFM version) to realize high efficiency at light load, soft-start and compensation circuits are implemented internally, which allow the device to be used with minimal external components.

The device has built-in protection features, such as cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown in case of excessive power dissipation.
