Monolithic Power Systems (MPS) EVQ9840 Evaluation Board

Monolithic Power Systems (MPS) EVQ9840 Evaluation Board is designed to evaluate MPQ9840 synchronous, step-down, and switch-mode converter. The MPQ9840 converter provides 3.5A of highly efficient output current with current-mode control. This converter features a wide input voltage range, switching frequency programmable from 350kHz to 2.5MHz, external soft start, and precision current limit. The MPQ9840 converter is available in a QFN-16 (3mmx4mm) package.
