EVQ8633B-H-LE-00A

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

Datasheet

Description

The EVQ8633B-H-LE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ8633B-H, a high-efficiency, monolithic, synchronous step-down converter.

The EVQ8633B-H-LE-00A can deliver up to 20A of continuous load current across a wide operating input voltage (V_IN) range. High efficiency can be achieved across a wide output current (I_OUT) load range.

The MPQ8633B-H utilizes an internally compensated constant-on-time (COT) control mode to provide fast transient response and ease loop stabilization. The MPQ8633B-H is available in a QFN-21 (3mmx4mm) package.

The EVQ8633B-H-LE-00A can be turned on or off via a remote on/off input (EN) referenced to ground. This input is compatible with popular logic devices.
