LMR516xx/LMR516xx-Q1 Power Converters

Texas Instruments LMR516xx/LMR516xx-Q1 SIMPLE SWITCHER® Power Converters are wide-VIN, easy-to-use synchronous buck converters capable of driving up to 0.6A and 1A load current. With a wide input range of 4V to 65V, the device is designed for various industrial applications for power conditioning from an unregulated source. The LMR516xx/LMR516xx-Q1 operates at 400kHz and 1.1MHz switching frequency to support relatively small inductors for an optimized design size. The LMR516xx/LMR516xx-Q1 has a PFM version to realize high efficiency at light load and an 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.
