MBI6023 is a 3x4-channel, constant-current, PWM-embedded sink driver for LED strips. MBI6023 provides constant current ranging from 3mA to 45mA for each output channel and are adjustable with three corresponding external resistors. Besides, MBI6023 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 grayscale 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 mode.
In addition, MBI6023 features a two-wire transmission interface to make cluster-to-cluster connection easier. To improve the transmission quality, MBI6023 provides phase-inverse output clock to eliminate the accumulation of signal pulse width distortion.
