5.5V, 1A Step-Down DC/DC Power Module in 3mm × 2.6mm Package

5.5V, 1A Step-Down DC/DC Power Module in 3mm × 2.6mm Package - LMZ10501


The LMZ10501 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 µSIP footprint package with an inductor. Internal current limit based soft-start function, current overload protection, and thermal shutdown are also provided.
