MY9262

Preliminary (Confidential) MY9262 16-Channel High Accuracy Constant Current LED Driver With MY-Semi 16bits Adaptive Pulse Density Modulation and Power Saving Control General Description The MY9262, 16-channel c o n s t a n t c u r r e n t LED driver with 16bits grayscale Adaptive Pulse Density Modulation (APDM) and power saving control, supports high quality LED video display applications. This distinctive APDM technology abates the non-ideal IOUT distortion due to non-symmetric transient responses and enhances the refresh rate by separating efficiently the frame waveform. The MY9262 features a f a s t 30MHz DCK input, allowing a wide LED dimming (on/off) range to be implemented. This 4-wire serial interface allows a microcontroller to configure the output channels using four inputs (DI, DCK, LAT, and GCK) and a data output (DO). DO allows multiple drivers to be cascaded and operated together. The device operates over a 3V to 5.5V input voltage range and provides 1 6 open-drain cons...
