MBI6651 Datasheet (Macroblock) - Step Down / 1A LED Driver

MBI6651, Step Down / 1A LED Driver

Small Outline Transistor The MBI6651 is a high efficiency, constant current and step-down DC/DC converter.

It is designed to deliver constant current to light up high power LED with only 4 external components.

With hysteretic PFM control scheme, MBI6651 improves the efficiency of light loading.
