- Create a custom design using the LMR516xx with the WEBENCH® Power Designer
The LMR516xx is a wide-V IN, easy-to-use synchronous buck converter capable of driving up to 0.6-A and 1-A load current. With a wide input range of 4 V to 65 V, the device is designed for a wide range of industrial applications for power conditioning from an unregulated source.
The LMR516xx operates at 400-kHz and 1.1-MHz switching frequency to support use of relatively small inductors for an optimized design size. The LMR516xx 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.
