Monolithic Power Systems (MPS) EVQ9842 Evaluation Board

Monolithic Power Systems (MPS) EVQ9842 Evaluation Board is designed to demonstrate the capabilities of MP/MPQ9842 regulators. This MP/MPQ9842GL is a 350kHz to 2.5kHz frequency programmable, synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFETs. The EVQ9842 evaluation board features a 5V to 36V input voltage range, a 5V output voltage, and a 2A output current with current mode control for fast loop response. This MP/MPQ9842GL comes with an Advanced Asynchronous Modulation (AAM) mode that helps to achieve high efficiency at light load conditions by scaling down the switching frequency. Typical applications include automotive systems and industrial power systems.
