MBI6659Q 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 LEDs. With the PWM control scheme, MBI6659Q eliminates external compensation design and makes the design simple.
The output current of MBI6659Q can be programmed by an external resistor and dimmed via pulse width modulation (PWM) or DC voltage through EN pin to achieve higher efficiency linear current modulation.
MBI6659Q features a completed protection design to handle faulty situations. The startup function limits the inrush current while the power is switched on Thermal shutdown, Thermal Foldback and Schottky diode short SDS) guard the system to be robust and keep the driver away from being damaged which results from LED open-circuited, short-circuited, and other abnormal events.
