ADP1073AR-5

Overview

The ADP1073AR-5 is a micropower DC-DC converter manufactured by Analog Devices Inc. It operates from an input supply voltage ranging from 1.0 V to 30 V, enabling use with single-cell battery sources. The device provides a fixed 5 V output and supports both step-up (boost) and step-down (buck) topologies. It features an internal 1 A power switch and requires very few external components for implementation. The unit is housed in an 8-Lead SOIC package.
