TPS61182RTET

Overview

The TPS61182RTET is a white LED driver IC designed for notebook displays, manufactured by Texas Instruments. It features a boost topology with six independent output channels, each capable of delivering up to 25 mA. The device supports an input voltage range of 5 V to 24 V and operates within a temperature range of -40°C to 85°C. Packaged in a 16-WQFN (3x3 mm) format, it integrates internal switches and PWM dimming control for efficient backlight regulation.

Feature Summary

• Six-channel constant current output for multi-LED string configurations
• Integrated high-efficiency boost converter with internal power switches
• Supports PWM dimming for precise brightness control
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Notebook display backlight systems
• Mobile device LCD backlighting
• Portable electronics requiring multi-string LED driving

Procurement Notes

Verify the suffix 'RTET' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the 5V–24V input requirement aligns with the system's battery or bus voltage architecture. Ensure thermal management strategies account for the WQFN package's thermal dissipation characteristics during continuous operation at maximum load conditions.

Selection Notes

Select this component when designing systems requiring six isolated LED strings driven from a single boost stage. Compare against TPS61181 if lower input voltage ranges are sufficient, as the TPS61182 supports higher input voltages up to 24V. Evaluate PCB layout constraints due to the small 3x3mm footprint and ensure adequate copper area for heat spreading.

Part Context

This part belongs to the TPS6118x family of white LED drivers from Texas Instruments. It shares functional similarities with the TPS61181 but differs in input voltage specifications. The RTET suffix indicates a specific reel-based packaging option distinct from the RTER variant, which may differ in reel diameter or manufacturer-specific handling requirements.

Replacement Considerations

The TPS61181RTET is a related variant within the same family; however, verify input voltage compatibility as the TPS61181 typically supports lower input ranges. Cross-reference datasheets to confirm pinout and electrical parameter alignment before substitution.
