Description
General part information
LMR54410 Series
The LMR544xx is a wide-VIN, easy-to-use synchronous buck converter capable of driving up to 1A and 0.6A load current. With a wide input range of 4V to 36V, the device is designed for a wide range of industrial applications for power conditioning from an unregulated source.
The LMR544xx operates at 1.1MHz switching frequency to support use of relatively small inductors for an optimized design size. The devices have 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.
