Product details

What this 16-channel linear LED driver actually does

The Texas Instruments TLC5921DAPR is a linear LED driver IC that integrates 16 constant-current sink outputs, each rated for 80 mA, with a shift-register interface clocked at 20 MHz. It accepts a supply voltage between 4.5 V and 5.5 V and drives outputs up to 17 V. The shift-register topology means you load grayscale or on/off data serially, then latch it to all outputs simultaneously — useful for LED panels, signage, or indicator arrays where you need independent control per channel without a separate PWM controller per LED.

Frequently asked questions

What are the alternatives to TLC5921DAPR?

The LM2703MF-ADJ/NOPB is a different class of part — a DC-DC boost regulator for backlight applications with a single 0.35 A output. It is not a functional second-source for the TLC5921DAPR, which is a 16-channel linear sink driver. For a pin-compatible or functionally equivalent alternate, check the TI TLC59xx family of shift-register LED drivers.
