Overview
The ADP2166ACPZ-1.5-R7 is a high-efficiency, step-down DC-to-DC regulator produced by Analog Devices Inc. This component is part of the ADP2165/ADP2166 series, known for its compact design and robust performance. The ADP2166ACPZ-1.5-R7 is housed in a 24-lead, 4 mm × 4 mm LFCSP (Lead Frame Chip Scale Package) with an exposed pad, making it suitable for applications requiring high power density and small footprint.
The regulator features an integrated 19 mΩ high-side FET and a 15 mΩ synchronous rectified FET, enabling efficient power conversion. It supports a wide input voltage range from 2.7 V to 5.5 V and can regulate the output voltage down to 0.6 V, with preset options including 1.5 V, as specified in this model.
