Hi, Allan,

Currently we don't have a similar device since IS31FL3731 is a matrix driver.

But we can afford similar solution: 1pc TLC5957+ 3 pcs P-MOS can drive 48*3=144 LEDs.

And thus solution has following advantages:
1/3 multiplexing ratio;
Pre-charge FET for ghosting reduction;
9bits(511 steps) to 16bits(65535 steps) PWM dimming selectable;
512 step adjustment for each color to get best white balance by software;
High system reliability (LED open detection, thermal shutdown);
Support multiple modules cascading.

Please check and tell me if you need more information.

Thanks.
Regards,
Kenneth

Hi, Allan,

You can refer to the following schematic for a solution driving 10*48 LEDs:
