Overview
MBI6024 is a PWM-embedded, 3 × 4-channel constant-current sink driver designed by Macroblock Inc. of Hsinchu, Taiwan. It is intended for LED strips, mesh displays and architectural lighting applications.
Unlike addressable LEDs that integrate the control circuit and LEDs into a single package, MBI6024 is a standalone driver IC connected to separate LEDs. This gives fixture manufacturers greater flexibility when selecting LED packages and designing custom 12-channel output arrangements.
The driver supports 16-bit grayscale mode, where Macroblock’s Scrambled-PWM technology divides the PWM cycle into 64 segments to increase the visual refresh rate while retaining 16-bit grayscale resolution.
Current Control
MBI6024 has the ability to digitally control the current of the connected LEDs. Use the 8-bit current control per colour to lower the brightness without sacrificing resolution, and tune the current of individual colours, allowing for more accurate colour mixing. This individual current control can be set when configuring your PixLite® Mk3 controller.

Advantages
- Presence of a clock allows for faster refresh rates
- Very high PWM rate allows for filming these pixels with cameras up to 391fps
- 16 bits of data for each color makes diming curves very smooth
- Phase-inversed clock output is intended to reduce accumulated pulse-width distortion in cascaded devices
- Three external current-setting resistors allow the fixture designer to select separate current levels for three groups of outputs
- Supports 3.3 V and 5 V driver supply system
Disadvantages
- No redundancy in data
