LP5012: solution that turn on/off LED by I/O pin

Hi David,

Do you want to look for a IC which has 12 I/O pins can control 12 channels separately? And could you please tell me what is the current required by the customer?

Btw, the RGB LED driver in TI normally has interface to control the output channel but I will try my best to see if there is such a device can satisfy the customer's requirement.

Hi Jared,

One I/O pin turns on/ off 12 channel LED. The totally current is 200mA.

Thanks & best regards,

Hi David,

I found a device LP5524 which has external I/O pin to control the output, but LP5524 only has 4 channels. I am curious about the customer's application, could you please tell the more detail requirement about customer? Because I think if customer only care about turn on/off output fast through one I/O pin. I think TLC59283 maybe can satisfy their requirement, since TLC59283 has a BLANK signal pin to control the output on/off through high/low level.

Hi David,

Can I know the end application of this requirement? Thanks and looking forward your comments.

Hi David,

Any update?

The application is Fundus photography.

Hi David,

Could you please tell me whether TLC59283 can satisfy the customer requirement since it seems that we don't have such a device which has external I/O to toggle the output?
