DESCRIPTION
The LMZ20502 Simple Switcher ^® Nano Module
regulator is an easy to use synchronous step-down
DC-DC converter capable of driving up to 2A of load
from an input of up to 5.5V, with exceptional
efficiency and output accuracy in a very small
solution size. The innovative package contains the
regulator and inductor in a small 3.5mm x 3.5mm x
1.9mm volume. Thus saving board space and
eliminating the time and expense of inductor
selection. The LMZ20502 requires few 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 using 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, thermal simulation,
and Build-It boards for easy design-in.
