MBI6024 is a 3x4-channel, constant-current, PWM-embedded sink driver for LED strips. MBI6024 provides constant current ranging from 3mA to 45mA for each output channel and are adjustable with three corresponding external resistors. Besides, MBI6024 can support both 3.3V and 5V power systems and sustain 17V at output channels.
With Scrambled-PWM (S-PWM) technology, MBI6024 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, MBI6024 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. The 16-bit gray scale mode provides 65,536 gray scales for each LED to enrich the color. Subject to the 16-bit gray scale mode, the 8-bit dot correction may adjust each LED by 256-step gain to compensate the LED brightness. Furthermore, the 10-bit gray scale mode provides 1,024 gray scales. Subject to the 10-bit gray scale mode, 6-bit dot correction may adjust each LED by 64-step gain.
In addition, MBI6024 features a two-wire transmission interface to make cluster-to-cluster connection easier. To improve the transmission quality, MBI6024 provides phase-inversed output clock to eliminate the accumulation of signal pulse width distortion. MBI6024 is also flexible for either manual-synchronization or auto-synchronization. The manual-synchronization is to maintain the synchronization of image frames between ICs. The auto-synchronization is to achieve accurate gray scale, especially when using the built-in oscillator.
