MAX38888ATD+

Overview

The MAX38888ATD+ is a reversible buck/boost switching voltage regulator designed for supercapacitor backup power applications. It operates with an input voltage range of 2.5 V to 5.5 V and provides a regulated output between 2.5 V and 5.0 V. The device supports a maximum output current of 500 mA in boost mode and 2.5 A in buck mode. Key electrical specifications include a quiescent current of 2.5 uA, a fixed switching frequency of 2 MHz, and an operating temperature range from -40°C to +125°C. It utilizes a 14-WFDFN package.
