16 Channel Adjustable Constant Current LED Driver

guitardenver — Fri, 10 Dec 2021 19:46:07 GMT

I'm looking for a drop in replacement for the TI TLC5926IPWPR LED driver.

It's 16 channel constant current LED driver. Max current is set via an external resistor, but we can also adjust the current via the SPI interface.

Does NXP have this as well? I do not need error detection feature. Just need to adjust the current via SPI bus.

5mA to 61mA output current.

Hello Matt,

There is not a drop in replacement for the TI TLC5926IPWPR currently available in our portfolio.

The closest device is the PCA9745B: 16-channel SPI serial bus 57 mA/20 V constant current LED driver:

There is a table with all NXP’s LED controllers available in the following document, page 3:

Best regards,

Tomas
