Description: 1A Dimmable LED Driver

Features

* 6~36V wide input voltage range
* Maximum 1A constant output current
* Patented fixed frequency analog dimming control - PWM-controlled brightness modulation - DC voltage-controlled brightness modulation
* 97% efficiency @ input voltage 12V, 350mA, 3-LED
* Hysteretic PFM operati

Applications

* It is designed to deliver constant current to light up high power LED with only 6 external components. With hysteretic PFM control scheme, MBI6653 eliminates external compensation design and makes the design simple. The output current of MBI6653 can be programmed by an external resistor and dimmed
