MAX1776EUA+T

The MAX1776EUA+T is a high-efficiency step-down (buck) converter manufactured by Analog Devices Inc. (formerly Maxim Integrated). It provides an adjustable output voltage ranging from 1.25V up to the input voltage (VIN), with a maximum input voltage of 24V. This device is capable of delivering up to 600mA of output current.

Key electrical specifications include a wide input voltage range of 4.5V to 24V and an output voltage that can be set anywhere between 1.25V and 24V. It features an internal 0.4 Ohm P-channel MOSFET and can operate at up to 100% duty cycle, minimizing dropout voltage. The converter boasts high efficiency, exceeding 95%, and maintains a low quiescent supply current of 15µA, making it suitable for battery-powered applications.

The MAX1776EUA+T operates at switching frequencies up to 200kHz, allowing for the use of small surface-mount inductors and capacitors. It includes features such as current limiting and thermal shutdown for protection. The device is housed in a compact 8-pin µMAX package, which is smaller than a traditional 8-pin SO package.

This step-down converter is well-suited for applications such as notebook computers, distributed power systems, keep-alive supplies, and hand-held devices where efficient voltage regulation and a small footprint are required.
