MBI6651 Product details

Description

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.The output current of MBI6651 can be programmed by an external resistor and LED dimming can be controlled via pulse width modulation (PWM) through DIM pin.In addition, the start-up function limits the
