Monolithic Power Systems MP24833A | Demoboard EV24833-A-N-00A

Description

The EV24833-A-N-00A Evaluation Board is designed to demonstrate the capabilities of MP24833-A. The MP24833-A is a 55V, 3A, white LED driver suitable for either step-downor inverting step-up/down applications. EV24833-A-N-00A is compatible with stepdown (Buck) and inverting step-up/down (Buckboost) 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-”
