Product Overview
The LP5009 is a Texas Instruments I2C RGB LED driver in the LED category. The LP5009 device variant provides 9 output channels with an integrated 12-bit PWM generator for each channel. The PWM frequency is 29 kHz, and the device supports Fast-mode I2C communication up to 400 kHz.
The VCC operating range is 2.7 V to 5.5 V, with EN, SDA, and SCL input logic compatibility for 1.8 V, 3.3 V, and 5 V power rails. OUTx output maximum voltage is 6 V, while recommended OUTx operation is 0 V to 5.5 V. Current sink capability is 25.5 mA per channel across the full VCC range, or 35 mA per channel when VCC is at least 3.3 V.
Packaging options include WQFN (RUK) 20-pin 3.00 mm × 3.00 mm and TSSOP (PW) 24-pin 7.80 mm × 4.40 mm. A 1 µF capacitor is required from VCAP to GND and should be placed close to the device. Applications include RGB LED indicators, multi-channel LED status displays, and I2C-controlled color lighting designs.

Procurement Notes
When requesting a quote for LP5009, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
