EVQ8633B-LE-00A

High Efficiency, 16V, 20A Synchronous Step-Down Converter Evaluation Board

Datasheet

Description

The EVQ8633B-LE-00A is an evaluation board for the MPQ8633B, a high-efficiency, monolithic, synchronous, step-down converter.

This EVB 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 adopts 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.
