LP8550TLX-E00/NOPB

LED Driver IC Overview

The LP8550TLX-E00/NOPB is a high-efficiency LED backlight driver IC from Texas Instruments, designed for portable applications. It features six independent current-regulated outputs capable of driving up to 50mA per channel. The device utilizes a boost DC-DC converter topology with an internal switch and supports PWM dimming control. Operating voltage ranges from 2.7V to 22V, with output voltages reaching up to 40V. It is housed in a compact 25-uSMD package and operates within a temperature range of -30°C to +85°C.

LED Driver IC Feature Summary

• Six-channel constant current regulation for uniform LED brightness
• Integrated boost DC-DC converter with internal power switch
• Supports PWM dimming for precise brightness control
• Compact surface-mount packaging suitable for space-constrained designs

LED Driver IC Applications

• Portable electronic device backlighting
• LCD panel illumination systems
• Mobile phone display drivers

LED Driver IC Procurement Notes

Verify the specific suffix E00 against the official datasheet to ensure correct tape-and-reel specifications and marking codes. Confirm that the 25-uSMD package variant matches the PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level before assembly planning.

LED Driver IC Selection Notes

Select this component when six independently regulated low-current LED channels are required. Ensure the input supply voltage stays within the 2.7V to 22V range. Verify that the 50mA per channel output current meets the LED string requirements. Consider the thermal performance of the 25-uSMD package under maximum load conditions.

LED Driver IC Part Context

This part belongs to the LP8550 series of LED lighting drivers. It shares functional similarities with other members like the LP8552 and LP8556 but differs in output current capacity and package options. The LP8550 specifically targets lower-power backlighting applications compared to higher-current variants in the same family.

LED Driver IC Replacement Considerations

Direct substitutes include LP8550TLE/NOPB which offers alternative packaging options such as cut tape or MouseReel. Cross-reference pinouts and electrical characteristics carefully when considering other LP855x series devices.
