Description

The EVQ8632-VE-20-00A is an evaluationboard for the MPQ8632GVE-20, a highefficiency monolithic synchronous step-downconverter.The EV board can deliver 20A continuous loadcurrent over a wide 8V to 18V operating inputrange. High efficiency can be achieved over awide output current load range.Constant-On-Time (COT) control modeprovides fast transient response and eases loopstabilization.This EV board can be turned on or shut down viaa remote ON/OFF input that is referenced toground. This input is compatible with popular logicdevices.
