Description
BCT3662 is a step up, two channel LED driver and each channel can support up to 6 LEDs for backlighting. It runs at 600kHz fixed switching frequency to reduce output ripple and EMI, improve conversion efficiency, and allow for the use of small external components. During the operation, the dimming control can be done through CTRL pin by PWM.
