Monolithic Power Systems MPQ8634B | Demoboard EV8634B-LE-00A

Description

The EVQ8634B-LE-00A is an evaluation board for the MPQ8634B, a high efficiency, monolithic, synchronous step-down converter.The EV board can deliver 20A continuous load current over a wide operating input range. High efficiency can be achieved over a wide output current load range.The MPQ8634B adopts internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization.This EV board can be turned on or off via a remote ON/OFF input (EN) that is referenced to ground. This input is compatible with popular logic devices.
