LP5012PWR

LED Driver IC Overview

The LP5012PWR is a 12-channel RGB LED driver from Texas Instruments' LP50xx family, housed in a 24-pin TSSOP package. It provides integrated color mixing and brightness control with pre-configuration capabilities. The device features 12-bit PWM resolution at a 29-kHz switching frequency to ensure smooth dimming effects. It operates within a VCC range of 2.7 V to 5.5 V and supports I2C communication. The EN, SDA, and SCL pins are compatible with 1.8-V, 3.3-V, and 5-V power rails.

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., PWR) against the official datasheet to confirm the package type and tape-and-reel specifications. Ensure compatibility with the target system's voltage levels and I2C bus requirements before procurement.

LED Driver IC Selection Notes

Select this component when a 12-channel constant-current driver with high-resolution PWM is required. Consider the LP50xx family variants if different channel counts or package options are needed for the specific PCB layout constraints.

LED Driver IC Part Context

This part belongs to the LP50xx series of ultra-low quiescent current RGB LED drivers. The series includes 9-channel and 12-channel variants designed for applications demanding efficient color control and minimal power consumption during operation.

LED Driver IC Replacement Considerations

Check for other LP50xx family members with matching channel counts. Verify pinout compatibility and electrical parameters against alternative suppliers' equivalent parts before substitution.
