Product Overview
The LP5012 is a Texas Instruments 12-channel RGB LED driver for LED control designs requiring multiple constant-current sink outputs. Each channel includes an integrated 12-bit PWM generator operating at 29 kHz, supporting fine brightness control across the device’s 12 output channels.
The recommended VCC operating range is 2.7 to 5.5 V, with OUTx voltage operation from 0 to 5.5 V and logic pin operation from 0 to 5.5 V on ADDRx, EN, SDA, and SCL. The device supports fast-mode I2C up to 400 kHz, and two hardware address pins, ADDR0 and ADDR1, allow up to four devices.
LP5012 is available in WQFN (RUK) 20-pin 3.00 mm x 3.00 mm and TSSOP (PW) 24-pin 7.80 mm x 4.40 mm packages. The VCAP pin requires a 1 µF external capacitor to GND placed close to the device. The recommended ambient operating temperature range is -40 to 85 °C.

Procurement Notes
When requesting a quote for LP5012, 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.
