Overview
The ADP2102YCPZ-2-R7 is a synchronous step-down DC-DC converter produced by Analog Devices Inc. This device is designed to convert an unregulated input voltage ranging from 2.7 V to 5.5 V to a lower regulated output voltage with high efficiency and accuracy. The ADP2102 is particularly suited for applications requiring low output voltages and high switching frequencies, making it ideal for USB-powered devices, WLAN and gateways, point of loads, and processor core power supplies.
