2.7V to 5.5V, 2A High Density Nano Module - LMZ20502

LMZ20502 (ACTIVE)

2.7V to 5.5V, 2A High Density Nano Module

 

Description

The LMZ20502 SIMPLE SWITCHER® Nano Module regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 2 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 LMZ20502 requires only five external components and has a pin-out designed for simple, optimum PCB layout. The LMZ20502 is a member of Texas Instruments’ SIMPLE SWITCHER family. The SIMPLE SWITCHER concept 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, please refer to the following document: SNOA401.
