Product Summary
The MIC4685BR is a high-efficiency 200kHz stepdown (buck) switching regulator. Power conversion efficiency of above 85% is easily obtainable for a wide variety of applications. The MIC4685BR achieves 3A of continuous current in the 7-pin SPAK package. The thermal performance of the SPAK allows it to replace TO-220s and TO-263s (D2PAKs) in many applications. The MIC4685BR allows for a high degree of safety. It has a wide input voltage range of 4V to 30V (34V transient), allowing it to be used in applications where input voltage transients may be present. Built-in safety features include over-current protection, frequency-foldback short-circuit protection, and thermal shutdown.
