Product Overview
The LP5024 is a Texas Instruments 24-channel RGB LED driver built around constant-current sink outputs. It is intended for LED designs requiring individually controlled OUT0 to OUT23 channels, with integrated 12-bit PWM generation at 29 kHz and a 3-phase PWM-shifting scheme. Global color bank control provides three programmable banks for R, G, and B channels.
The device operates from a 2.7 to 5.5 V VCC input range and supports EN, SDA, and SCL logic pin compatibility with 1.8 V, 3.3 V, and 5 V power rails. Output voltage support includes a 6 V maximum feature rating and a recommended OUTx operating range of 0 to 5.5 V. Fast-mode I2C operation supports bus speeds up to 400 kHz, with two external address pins allowing up to four devices on the bus.
LP5024 is offered in a 32-pin VQFN package with a 4.00 mm x 4.00 mm body size. Assembly guidance from the extracted facts includes leaving unused OUT0 to OUT23 pins floating and connecting unused SCL or SDA pins to GND or VCC. The VCAP pin requires a 1 uF capacitor to GND placed close to the device.

Procurement Notes
When requesting a quote for LP5024, 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.
FAQ
What type of LED driver is the LP5024?
The LP5024 is a Texas Instruments 24-channel RGB LED driver with constant-current sink outputs. It includes integrated 12-bit PWM generation for each channel and supports a 29 kHz PWM frequency.
What supply voltage range does LP5024 support?
The LP5024 VCC operating range is 2.7 to 5.5 V. Its recommended VCC input voltage is also 2.7 to 5.5 V across the specified operating ambient temperature range.
How much sink current can each LP5024 channel provide?
The LP5024 supports 25.5 mA per channel across the full VCC range. When VCC is at least 3.3 V, the maximum sink current option supports 35 mA per channel.
How many LP5024 devices can share one I2C bus?
Using the two external hardware address pins, up to four LP5024 devices can be placed on the same bus. The I2C interface supports fast-mode bus speeds up to 400 kHz.
What should be done with unused LP5024 pins?
Unused OUT0 to OUT23 pins can be left floating. If SCL or SDA are not used, the extracted pin handling guidance states that each unused I2C line should be connected to GND or VCC.
