Each of the 16 outputs sinks up to 120 mA, with a 17 V output ceiling that covers most multi-LED series strings in backlight applications. The internal switches are integrated, so no external FETs are needed per channel — the driver handles the current regulation and PWM dimming on-chip. ## Lifecycle and compliance posture Marked as Active on the lifecycle status — Texas Instruments continues to manufacture this part with no announced end-of-life. ## Why the LM2703MF-ADJ/NOPB is not a drop-in The LM2703MF-ADJ/NOPB is a single-output boost regulator (step-up DC/DC), not a multi-channel linear sink — it drives one LED string at 0.35 A with a different topology and pinout. The TLC5940RHBR controls 16 independent channels simultaneously, while the LM2703 handles one channel with an external inductor; they serve different backlight architectures.","metaTitle":"TLC5940RHBR 16-Channel LED Driver, 120 mA, 30 MHz, VQFN","metaDescription":"Texas Instruments TLC5940RHBR linear LED driver, 16 outputs at 120 mA each, 30 MHz shift register, 3-5.5 V supply.
