Product Overview

The LMR10520XSD/NOPB is a SIMPLE SWITCHER® monolithic high frequency PWM step-down DC-to-DC Converter provides all the active functions to provide local DC-to-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components, the LMR10520 is easy to use. The ability to drive 2A load with an internal 150mR PMOS switch results in the best power density available. The world-class control circuitry allows on-times as low as 30ns, thus supporting exceptionally high frequency conversion over the entire 3 to 5.5V input operating range down to the minimum output voltage of 0.6V. The LMR10520 is internally compensated, so it is simple to use and requires few external components. Even though the operating frequency is high, efficiencies up to 93% are easy to achieve. External shutdown is included, featuring an ultra-low stand-by current of 30nA.
