TPS61180RTET

Overview

The TPS61180RTET is a white LED driver IC designed for notebook displays, manufactured by Texas Instruments. It utilizes a boost topology with an integrated MOSFET and operates within a supply voltage range of 5 V to 24 V. The device provides six independent output channels, each capable of delivering up to 25 mA of current. It supports PWM dimming control and functions at a switching frequency of 1 MHz. The maximum output voltage reaches 38 V, while the operating temperature range spans from -40°C to +85°C. The component is housed in a 16-WQFN package.

Feature Summary

• Integrates a high-side switch and boost converter for efficient power management
• Supports precise PWM dimming for display backlight regulation
• Provides six independent regulated current outputs for multi-string LED arrays

Applications

• Notebook display backlight systems
• Portable computer LCD modules
• Multi-string white LED lighting circuits

Procurement Notes

Verify the specific suffix 'RTER' against official Texas Instruments documentation to confirm reel packaging specifications and moisture sensitivity level. Ensure compatibility with RoHS3 standards and check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing notebook displays requiring six independent LED strings with integrated power switches. It is suitable for applications needing wide input voltage tolerance and precise PWM dimming control. Consider the 16-WQFN package size for space-constrained PCB layouts and verify thermal dissipation requirements for the integrated MOSFET under maximum load conditions.

Part Context

This part belongs to the TPS6118x series of WLED drivers optimized for portable computing devices. It shares architectural similarities with the TPS61181 and TPS61182 but differs in specific current ratings and feature sets. The series targets the notebook market, offering a compact solution for driving multiple LED strings without external power transistors.

Replacement Considerations

The TPS61181RTET is documented as a parameter-equivalent substitute. Verify functional differences regarding output current capabilities and ensure pin-to-pin compatibility before implementation.
