Product Introduction

Overview

The ADP2164ACPZ-2.5-R7 is a high-efficiency, synchronous step-down DC-to-DC regulator produced by Analog Devices Inc. This regulator is designed to provide a continuous output current of up to 4 A and is packaged in a compact 4 mm x 4 mm LFCSP (Lead Frame Chip Scale Package). It operates with an input voltage range of 2.7 V to 6.5 V and can regulate the output voltage down to 0.6 V, with preset options including 2.5 V, among others. The ADP2164 is ideal for applications requiring high current density and efficiency in a small footprint.
