Overview
The ADP2166ACPZ-R7, produced by Analog Devices Inc., is a high-efficiency, current-mode control, step-down DC-to-DC regulator. This regulator integrates a 19 mΩ high-side FET and a 15 mΩ synchronous rectified FET, making it suitable for applications requiring high power density and small form factor. The device is available in a 24-lead, 4 mm × 4 mm LFCSP package and supports a wide range of output voltages with preset options of 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, and 1.0 V. It operates with an input voltage from 2.7 V to 5.5 V and can regulate the output voltage down to 0.6 V.
