Product details

What this linear LED driver does on your board

The Texas Instruments LP5569ARTWR is a 9-channel linear LED driver with a switched-capacitor charge-pump topology, generating a regulated output voltage from a 2.5 V to 5.5 V input without an external inductor. Each of the nine outputs sinks up to 25.5 mA, controlled via an I²C interface or direct PWM dimming.

Each of the nine channels is independently programmable via I²C for current level and on/off timing. The 25.5 mA per channel is the maximum sink current; you can set lower values through the internal registers. Because this is a linear driver (not a switching regulator), the efficiency is (V_LED / V_supply). For battery-powered gear, that matters; for a mains-powered indicator panel, it's fine.

For production BOMs, this part is a low-risk line item — no end-of-life clock ticking, no broker dependency.

Frequently asked questions

Is LP5569ARTWR active or obsolete?

Active. Texas Instruments lists the LP5569ARTWR as Active with no end-of-life or last-time-buy notice. It is ROHS3 compliant.

What is the output current of LP5569ARTWR?

25.5 mA per channel, across all nine outputs. Each channel is independently programmable via I²C to any value from 0 to 25.5 mA in 256 steps.

What is the equivalent for LP5569ARTWR?

The LM2703MF-ADJ/NOPB is a different class of part — a single-output boost regulator for backlight applications, not a multi-channel linear driver. There is no pin-compatible second source listed for the LP5569ARTWR. For a functional equivalent, look for other TI 9-channel linear LED drivers with I²C control in the same 24-WQFN package, but verify pinout and register map compatibility from the respective datasheets.

What is LP5569ARTWR's listed type on this component line?

Linear LED driver. It uses a switched-capacitor charge-pump topology to generate the LED supply voltage.

What is LP5569ARTWR's listed dimming on this component line?

I²C and PWM dimming. The I²C interface controls per-channel brightness registers; a dedicated PWM input pin is also available for external dimming control.
