The MBI6023 is a 3×4-channel, constant-current, PWM-embedded sink driver for LED strips.
MBI-6023 provides constant current ranging from 3mA to 45mA for each output channel and are adjustable with three corresponding external resistors. Besides, MBI-6023 can support both 3.3V and 5V power systems and sustain 17V at output channels.

With Scrambled-PWM (S-PWM) technology, MBI6023 enhances pulse width modulation by scrambling the “on” time into several “on” periods to increase visual refresh rate at the same gray scale performance. Besides, the gray scale clock (GCLK) is generated by the embedded oscillator. Moreover, MBI6023 provides two selectable gray scale modes to trade off between image quality and transmission: 16-bit gray scale mode and 10-bit gray scale
