MAX640ESA-T Description

Short technical summary and product information.

The Analog Devices MAX640ESA-T is a high-efficiency, low quiescent current step-down switching regulator. It is designed to provide up to 225mA of output current.

 

This device operates with an input voltage range from 4V to 11.5V. The MAX640ESA-T offers a preset output voltage of 3.3V, or the output can be user-adjusted to any voltage from 1.3V up to the input voltage. It utilizes a current-limiting pulse-frequency-modulated (PFM) control scheme for high efficiency across a wide range of load currents, while consuming only 10µA of supply current.

 

The MAX640ESA-T features an internal 1A power MOSFET switch, making it suitable for minimum-component, low- and medium-power applications. It is available in an 8-SOIC surface mount package.

 

Applications include 9V battery to 3.3V conversion, high-efficiency linear regulator replacement, and portable instruments.
