Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free specifications. Confirm that the ordering code matches the specific tape-and-reel packaging variant required for automated assembly processes. Cross-reference the datasheet revision date to ensure compatibility with current design requirements and regulatory updates.

Selection Notes

Select this component when designing for notebook or portable displays requiring six distinct LED channels. Ensure the system input voltage remains within the 5 V to 24 V operational window. Verify that the PCB layout accommodates the 16-WQFN package dimensions and thermal requirements. Confirm that the application demands PWM dimming capabilities and a maximum output voltage capability of 38 V.

Part Context

This device belongs to the TPS6118x family of LED drivers from Texas Instruments. It shares architectural similarities with the TPS61180 but offers specific channel configurations and performance characteristics tailored for notebook applications. The RTERG4 designation indicates a specific reel-based packaging format compliant with environmental standards.

Replacement Considerations

The TPS61180RTER is a related device within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure that the alternative part meets the specific output current and voltage requirements of the target design.
