LP8556TME-E05/NOPB

LED Driver IC Overview

The LP8556TME-E05/NOPB is a six-channel high-efficiency LED backlight driver from Texas Instruments, designed for portable applications. It operates within an input voltage range of 2.7 V to 20 V and supports output currents up to 25 mA per channel. The device utilizes a boost topology with adjustable switching frequencies of 312 kHz, 625 kHz, or 1.25 MHz. Control is managed via I2C interface, and it features PWM dimming capabilities. Packaged in a DSBGA-20 format, it functions reliably between -30°C and +85°C.

LED Driver IC Procurement Notes

Verify the specific suffix E05 against the official datasheet to confirm internal configuration differences. Ensure the DSBGA-20 package footprint matches the PCB layout requirements. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when a compact solution for multiple LED strings is required. The I2C interface reduces pin count compared to parallel control methods. Consider the thermal performance of the DSBGA-20 package in dense layouts. Verify that the input voltage range aligns with the system power supply architecture.

LED Driver IC Part Context

This part belongs to the LP8556 series of LED lighting drivers. Variants such as LP8556TMX-E05/NOPB share similar core functionality but differ in packaging style. The series targets efficiency-critical portable electronics requiring precise multi-channel regulation.

LED Driver IC Replacement Considerations

LP8556TMX-E05/NOPB serves as a tape-and-reel alternative with identical electrical characteristics. LP8556TME-E02/NOPB offers similar features but may have different factory packaging quantities.
