Description

The EVQ8633B-H-LE-00A is an evaluation board for the MPQ8633B-H, which is a highefficiency, monolithic, synchronous, step-down converter.The EVQ8633B-H-LE-00A can deliver 20A of continuous load current over a wide operating input range. High efficiency can be achieved over a wide output current load range.The MPQ8633B-H utilizes an internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization.This EVB can be turned on or off via a remote on/off input (EN) referenced to ground. This input is compatible with popular logic devices.
