Monolithic Power Systems (MPS) MPQ4418-AEC1 Synchronous Step-Down Converter is a high-efficiency, synchronous, rectified, switch-mode, step-down converter with integrated power MOSFETs. The MPQ4418-AEC1 can deliver up to 0.6A of continuous output current across a wide 4V to 36V input voltage range, with excellent load and line regulation.

The Synchronous mode of the MPQ4418-AEC1 offers high efficiency across the entire output current load range. The Current Control mode provides a fast transient response and improved loop stabilization.

The MPQ4418 includes protection features such as over-current protection (OCP) and thermal shutdown (TSD).

The Monolithic Power Systems (MPS) MPQ4418-AEC1 Synchronous Step-Down Converter is a compact solution that requires a minimal number of readily available, standard external components, and is available in a small TSOT23-8 package. The device is AEC-Q100 qualified for use in automotive applications.
