TPS61181RTERG4

Overview

The TPS61181RTERG4 is a Texas Instruments LED driver IC featuring six independent outputs with a maximum output current of 25mA per channel. It utilizes a boost DC-DC converter topology to drive white LEDs, supporting an input voltage range from 5V to 24V and delivering up to 38V at the output. The device operates at a switching frequency of 1MHz and incorporates internal power switches. It supports PWM dimming control and is housed in a 16-WQFN (3x3) package.

Feature Summary

Six-channel constant current regulation for multi-string LED arrays
Integrated boost converter with internal high-side switches
Supports PWM dimming for precise brightness control

Applications

Notebook display backlighting
Portable electronic device illumination
White LED driver circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging variations. Ensure the supplier provides valid traceability documentation matching the TPS61181RTERG4 part number before finalizing acquisition.

Selection Notes

Select this component when designing systems requiring six independent LED channels driven by a single boost regulator. Consider the 1MHz switching frequency for passive component size optimization. Evaluate the 5V to 24V input range against system power supply capabilities. Verify thermal performance within the specified -40°C to 85°C operating temperature range for the target application environment.

Part Context

This part belongs to the TPS61181 family of WLED drivers designed primarily for notebook displays. It shares architectural similarities with the TPS61180 and TPS61182 series but offers specific current ratings and input voltage characteristics tailored for portable computing backlight applications.

Replacement Considerations

Public confirmed substitute part numbers include TPS61181RTET and TPS61181ARTET. These variants share the same functional architecture and pinout but differ in output current specifications and input voltage ranges.
