Monolithic Power Systems (MPS) EV24833-A-N-00A Evaluation Board
Monolithic Power Systems (MPS) EV24833-A-N-00A White LED Driver Evaluation Board is intended to demonstrate the capabilities of the MP24833-A driver. The MP24833-A is a 55V, 3A, white LED driver suitable for either step-down or inverting step-up/down applications.The MPS EV24833-A-N-00A Evaluation Board is compatible with step-down (Buck) and inverting step-up/down (Buck-boost) applications.
• For step-down application, short “JP1”, open “JP2”, connect LED load to “LED+” and “LED-”
• For step-up/down application, short “JP2”, open “JP1”, connect LED load to “LED+” and “LED-”
