The LMZ20501 nano module regulator is an easy-to-use synchronous step-down DC/DC converter capable of driving up to 1 A of load from an input of up to 5.5 V, with exceptional efficiency and output accuracy in a very small solution size. The innovative package contains the regulator and inductor in a small 3.5 mm × 3.5 mm × 1.75 mm volume, thus saving board space and eliminating the time and expense of inductor selection. The LMZ20501 requires only five external components and has a pin-out designed for simple, optimum PCB layout. The device provides for an easy to use complete design with a minimum number of external components and the TI WEBENCH design tool. TI’s WEBENCH tool includes features such as external component calculation, electrical simulation, and WebTherm. For soldering information, see SNOA401.
