7.1 Overview

The LMZ10501 SIMPLE SWITCHER® power converter nano module is an easy-to-use step-down DC-DC solution capable of driving up to 1A 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 8-pin LLP footprint package with an integrated inductor. The LMZ10501 operates in fixed 2.0-MHz PWM (Pulse Width Modulation) mode, and is designed to deliver power at maximum efficiency. The output voltage is typically set by using a resistive divider between the built-in reference voltage VREF and the control pin VCON. The VCON pin is the positive input to the error amplifier. The output voltage of the LMZ10501 can also be dynamically adjusted between 0.6 V and 3.6 V by driving the VCON pin externally. Internal current limit based soft-start function, current overload protection, and thermal shutdown are also provided.
