Looking for 3 channel low side LED driver

Jonathan Navor

Hi Guys,

Good day. Our customer is working on a project that requires a 3 channel low side LED driver, requires 2 x RGBs connected in series (for each color).

They need 50mA max output, 20mA typical, independent PWM capability for dimming and color mixing, and SPI/I2C communication with my microcontroller.

The nearest possible device that have this specification is TPS929120-Q(High Side driver), but the customer need the low side driver version of this. Is there any counter part of the high side driver that TPS929120-Q have?

Thank you in advance for the support.

Best regards,

Jonathan

Hi, a 4, 8 or 12 channel low side driver may work as well if you do not have the 3 channel. Does TI have something like that?

You can reference TLC6C5716/24 or TLC6C5712.

Hello thank you for helping. Are all of these (especially the 12channle one) capable of independent diming for each channel?
