MAX38888ATD+T is a high-efficiency reversible buck/boost regulator from Analog Devices (Maxim Integrated), belonging to the Continua™ family of backup power regulators. It is designed to efficiently transfer power between storage elements (supercapacitors or capacitor banks) and system supply rails, ideal for backup power applications.
Core Features: It operates with an input voltage range of 0.8V to 5.5V, delivering an adjustable output voltage of 2.5V to 5V and a peak output current of 2.5A (discharge) / 0.5A (charge). With a 2MHz switching frequency and up to 95% efficiency, it features ultra-low 2.5µA quiescent current in ready mode. The chip supports programmable voltage and current thresholds with ±2% accuracy, comes in a compact 14-pin TDFN (3mm×3mm) exposed pad package, and operates from -40°C to +125°C, complying with RoHS and MSL 1 (unlimited) standards. It efficiently transfers power between storage elements (supercapacitors/capacitor banks) and system supply rails in reversible buck/boost operations.
Key Applications: Widely used in handheld industrial equipment, portable computers, portable devices with removable batteries, backup power systems, and low-power electronic devices. It efficiently manages supercapacitor charging and discharging, ensuring stable power supply when the main power is interrupted, and is also suitable for energy storage systems and portable electronic equipment requiring reliable backup power, making it the preferred choice for high-reliability backup power regulation applications.
