3 Description
The LMZ10501 SIMPLE SWITCHER® nano module
is an easy-to-use step-down DC-DC solution capable
of driving up to 1-A load in space-constrained
applications. Only an input capacitor, an output
capacitor, a small VCON filter capacitor, and two
resistors are required for basic operation. The nano
module comes in an 8-pin LLP footprint package with
an inductor. Internal current limit based soft-start
function, current overload protection, and thermal
shutdown are also provided.
