Hi,

What cost-effective/ most-efficient solution do you suggest for an application that needs more than a 48 channel LED driver.

Hi Daviel,

How many LEDs need and what application for the design? 48 channels is the max channel number for our device. If more channel is require, you could cascade multiple TLC59581 or use matrix structure.

Hi Daviel,

Could you help to introduce more background, is it used into panel backlighting or other thing? And for the LED structure, does it need control all LEDs individually, or cascading some and paralleling some?

Here is an AN that you could refer that using matrix structure to drive a large number of LEDs individually.
