Product Description
MBI6661 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 5 external ponents. By hysteretic PFM control scheme,
GD: SOP8L-150-1.27
MBI6661 omits the external pensation design.
The output current of MBI6661 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 inrush...
