Overview
The ADP2166ACPZ-1.0-R7 from Analog Devices Inc. is a high-efficiency, current mode control, step-down DC-to-DC regulator. This component is designed to provide a compact and reliable power management solution, integrating a 19 mΩ high-side FET and a 15 mΩ synchronous rectified FET. It operates over a wide input voltage range of 2.7 V to 5.5 V and can regulate the output voltage down to 0.6 V, with preset options including 1.0 V, among others. The regulator is housed in a 24-lead, 4 mm × 4 mm LFCSP package, making it suitable for applications requiring high power density and small footprint.
