DESCRIPTION
The output current of MBI6653 can be programmed by an external resistor and dimmed via pulse width modulation (PWM) through PWMD pin. In addition, a novel fixed frequency analog dimming method is proposed and offered by the device. Users can achieve higher efficiency linear current modulation from 5% to 100% of preset current by applying either PWM-controlled or DC voltage-controlled brightness modulation.
