Monolithic Power Systems (MPS) EVBL9840-L-00A Evaluation Board

Monolithic Power Systems (MPS) EVBL9840-L-00A Evaluation Board is designed to demonstrate the capabilities of the MP9840 and the MPQ9840. The MP9840 Synchronous Step-Down Converters are high-frequency, rectified, switch-mode converters providing built-in power MOSFETs. The MP9840 delivers 3.5A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range.

The MPS EVBL9840-L-00A Evaluation Board supplies an integrated MPS power inductor. The fully assembled and tested evaluation board develops 3.3V of output voltage (V_OUT) and up to 3.5A of load current across the entire V_IN range.
