LP8556TME-E02/NOPB

LED Driver IC Overview

The LP8556TME-E02/NOPB is a six-channel high-efficiency LED backlight driver from Texas Instruments, housed in a DSBGA-20 package. It operates on an input voltage range of 2.7 V to 20 V with a maximum supply current of 3.65 mA. The device supports adjustable switching frequencies of 312 kHz, 625 kHz, and 1.25 MHz. Each channel provides a constant output current of 25 mA. Control is managed via I2C interface, supporting PWM dimming and enable/shutdown functions.

LED Driver IC Feature Summary

LED Driver IC Procurement Notes

Verify the specific suffix E02 against the official datasheet to confirm the exact electrical characteristics and pinout configuration. Ensure the DSBGA-20 package compatibility with your PCB footprint. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component when a six-channel solution with low quiescent current is required. The 2.7 V to 20 V input range suits single-cell lithium battery systems. The I2C interface allows for flexible brightness control without additional GPIOs. Consider the DSBGA-20 package for space-constrained designs.

LED Driver IC Part Context

Part of the LP8556 series designed for high-efficiency LED backlighting. The series offers multiple variants with different output currents and input voltage ranges. This specific model focuses on balanced performance for standard LCD applications with moderate current requirements.

LED Driver IC Replacement Considerations

Check for LP8556 variants with different suffixes (e.g., E04, E09) if higher output current or wider input voltage is needed. Verify pin-to-pin compatibility before substitution. Consult the TI selection guide for alternative drivers within the same family.
