Monolithic Power Systems (MPS) EVBL9841-L-00A Evaluation Board

Monolithic Power Systems (MPS) EVBL9841-L-00A Evaluation Board features an integrated MPS power inductor and demonstrates the capabilities of the MP9841 and MPQ9841 Converters. The MP9841 Synchronous Step-Down Converters offer a switch-mode and built-in power MOSFETs. The compact solution achieves 1A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range. Advanced asynchronous modulation (AAM) mode achieves high efficiency under light-load conditions by scaling down the switching frequency (f_SW) to reduce the switching and gate driver losses.

The MPS EVBL9841-L-00A Evaluation Board is fully assembled and tested, generating 3.3V of output voltage (V_OUT) and up to 1A of load current across the entire V_IN range.
