Description

The EVQ8633B-L-00A is an evaluation boardfor the MPQ8633B, a high efficiency, monolithic,synchronous step-down converter.The EV board can deliver 20A continuous loadcurrent over a wide operating input range. Highefficiency can be achieved over a wide outputcurrent load range.The MPQ8633B adopts internally compensatedconstant-on-time (COT) control mode thatprovides fast transient response and eases loopstabilization.This EV board can be turned on or off via aremote ON/OFF input (EN) that is referenced toground. This input is compatible with popular logicdevices.
