Description

The EV8795-LE-00A is an evaluation board designed to demonstrate the capabilities of the MP8795, a high-efficiency, monolithic, synchronous, step-down converter. The MP8795 can deliver up to 15A of continuous output current (IOUT) across a wide input voltage (VIN) range,and is highly efficient across a wide output current range (up to 15A). Internally compensated constant-on-time (COT) control provides fast transient response and eases loop stabilization. The remote enable (EN) input referenced to ground turns the part on and off. This input is compatible with most popular logic devices. The MP8795 is available in a QFN-21 (3mmx4mm) Package.
