Add To BomLMR51420YFDDCR General Description
The LMR51420 is a wide-VIN, easy-to-use SIMPLE SWITCHER power converter synchronous buck converter capable of driving up to 2-A load current. With a wide input range of 4.5 V to 36 V, the device is suitable for a wide range of industrial applications for power conditioning from an unregulated source.
The LMR51420 operates at 500-kHz and 1.1-MHz switching frequency to support use of relatively small inductors for an optimized solution size. The device has a PFM version to realize high efficiency at light load and 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 allows the device to be used with minimum 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. The LMR51420 is available in a 6-pin SOT-23 package.
