Overview
The ADP2165ACPZ-2.5-R7, produced by Analog Devices Inc., is a high-efficiency, current mode control, step-down DC-to-DC regulator. This component is part of the ADP2165/ADP2166 family, known for its flexibility and high-performance capabilities. It integrates a 19 mΩ high-side FET and a 15 mΩ synchronous rectified FET, making it suitable for a wide range of power management applications. The regulator is available in a compact 24-lead, 4 mm × 4 mm LFCSP package, enhancing power density and reducing the size of external components such as inductors.
