Monolithic Power Systems (MPS) EV24881-S-00A Driver Evaluation Board

Monolithic Power Systems (MPS) EV24881-S-00A Driver Evaluation Board is designed to demonstrate the capabilities of the MP24881, a 60V, monolithic, synchronous step-down LED driver with a built-in N-channel MOSFET and rectifier. It delivers up to 1.1A of continuous output current (IOUT) to high-power LEDs. The wide 10V to 60V input voltage (VIN) range accommodates a variety of step-down lighting applications. Hysteretic current mode control of the Monolithic Power Systems (MPS) MP24881 achieves very fast transient response and eliminates the need for loop compensation design.
