Description

The EV8764GLE-L-00A is an evaluation board for the MP8764GLE, a high efficiency monolithic synchronous step-down converter.

The EV bo rd can deliver 12A continuous load current over a wide 4.5V to 18V operating input range. High efficiency can be achieved over awide output current load range.

Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.

This EV board can be turned on or shut down via a remote ON/OFF input that is referenced to ground. This input is compatible with popularlogic devices.

Features

  • Wide 4.5V to 18V Operating Input Range
