The output current can be preset through an external resistor. Moreover, the preset current of MBI5042 can be further programmed to 64 gain steps for LED global brightness adjustment. GTS: TSSOP24L-173-0.65 QFN With Scrambled-PWM (S-PWM) technology, MBI5042 enhances Pulse Width Modulation by scrambling the “on” time into several “on” periods. The enhancement equivalently increases the visual refresh rate. When building a 16-bit color depth video, S-PWM reduces the flickers and improves the fidelity. MBI5042 offloads the signal timing generation of the host controller which just needs to feed data into GFN: QFN24L-4*4-0.5 drivers. MBI5042 drives the corresponding LEDs to the brightness specified by image data. With MBI5042, all output channels can be built with 16-bit color depth (65,536 gray scales). Each LED’s brightness can be calibrated enough from minimum to maximum brightness with compensated gamma correction or LED deviation information inside the 16-bit image data. Macroblock, Inc. 2014 Floor 6-4, No.18, Pu-Ting Rd., Hsinchu, Taiwan 30077, ROC.

Please refer to JEDEC JESD51. ** Operation at the maximum rating for extended periods may reduce the device reliability; therefore, the suggested operation temperature of the device is under 125°C. Note: The performance of thermal dissipation is strongly related to the size of thermal pad, thickness and layer numbers of the PCB. The empirical thermal resistance may be differe.
