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.
