3 Description
The LMZ20502 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
device provides 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, refer to the following
