TLC5927: More than 16-channels Constatnt current LED sink Driver

Marcin Brylak

Part Number: TLC5927

Dear TI,

I am using now your TLC5927 Driver but for new project I have to drive 400 LEDs and PCB need to be small. Can you please recommend an IC Driver with more than 16-channels,around 50mA pro channel, with SPI Interface and small footprint/package.

Tanks a lot

Hi Marcin,

What is the connection manner and is this the LED matrix?

If so, what is the pitch of the LED matrix?

Generally, we need to know the size of the matrix(row and column), the pitch, and channel current.

Regards!

Shawn.

C1700019_PADS.pdfHi Shawn,

We have 400 LED and which need to be control separately. We need 50 mA or more per each LED.

Hi Marcin,

We have no device that channels more than 16 with the current 50 mA or more per channel. Below is my suggestions:

Do you need the LED dimming function?

If so,

TLC594x is a better choice

If not,

TLC592x is a better choice

Regards!

Shawn.
