3 Description
The LMZ10500 SIMPLE SWITCHER^® nano module
is an easy-to-use step-down DC-DC solution 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 LLP footprint package with
an integrated inductor. Internal current limit based
soft-start function, current overload protection, and
thermal shutdown are also provided.
