3 Description

The LMZ10500 nano module is an easy-to-use step-

down DC/DC design capable of driving up to 650-mA

load in space-constrained applications. Only an input

capacitor, an output capacitor, a small V

CON

filter

capacitor, and two resistors are required for basic

operation. The nano module comes in an 8-pin µSiP

footprint package with an integrated inductor. Internal

current limit based soft-start function, current overload

protection, and thermal shutdown are also provided.
