Monolithic Power Systems (MPS) EVQ9843 Evaluation Board

Monolithic Power Systems (MPS) EVQ9843 Evaluation Board is designed to demonstrate the capabilities of the MP/MPQ9843 regulators. These MP/MPQ9843 regulators are 350kHz to 2.5MHz frequency programmable, synchronous, step-down switching regulators with integrated internal high-side and low-side power MOSFETs. The EVQ9843 evaluation board features a 5V to 36V input voltage range, 5V output voltage, and 3V output current. This evaluation board comes with an Advanced Asynchronous Modulation (AAM) mode helps to achieve high efficiency at light load conditions by scaling down the switching frequency. Typical applications include automotive systems and industrial power systems.
