Description

General part information

LMR51410 Series

The LMR514xx is a wide-VIN, easy-to-use synchronous buck converter capable of driving up to 0.6A and 1A load current. With a wide input range of 4V to 42V, the device is designed for a wide range of industrial applications for power conditioning from an unregulated source.

The LMR514xx operates at 400kHz and 1.1MHz switching frequency to support use of relatively small inductors for an optimized design size. The LMR514xx has a PFM version to realize high efficiency at light load and a FPWM version to achieve constant frequency and small output voltage ripple over the full load range. 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.
