MBI6653 Description
MBI6653 is a step-down constant-current high-brightness LED driver to provide a cost-effective design solution for interior/exterior illumination applications. It is designed to deliver constant current to light up high power LED with only 6 external ponents. With hysteretic PFM control scheme, MBI6653 eliminates external pensation design and makes the design simple.
