TPS61180RTETG4

Overview

The TPS61180RTETG4 is a white LED driver IC designed for notebook displays. It features six independent boost channels with an integrated 1.5A power switch. The device operates from a 5V to 24V input supply and delivers up to 38V output voltage. Each channel provides a regulated 25mA output current. It supports PWM dimming at a 1MHz switching frequency. The component is housed in a 16-WQFN package and functions within a -40°C to +85°C temperature range.

Feature Summary

• Six independent high-side boost channels for multi-segment backlighting
• Integrated 1.5A power MOSFET for efficient energy transfer
• Precision constant current regulation across all channels
• Wide input voltage compatibility for various system architectures

Applications

• Notebook display backlight systems
• Multi-zone LED lighting control
• Portable electronic device illumination
• High-brightness LCD backlight drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the G4 suffix aligns with current environmental compliance standards required by your project. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring independent control of multiple LED strings without external switches. Ensure the input voltage range matches the battery or bus supply available in the target application. Consider the thermal performance of the WQFN package relative to the expected ambient operating conditions and PCB copper area for adequate heat dissipation during continuous operation.

Part Context

This device belongs to the TPS6118x family of LED drivers, which are optimized for portable computing applications. It shares functional similarities with the TPS61181 and TPS61182 models but may differ in specific pin configurations or internal protection features. The RTETG4 designation indicates a specific surface-mount package variant compliant with lead-free manufacturing processes defined by Texas Instruments.

Replacement Considerations

Public confirmed substitute part numbers include TPS61180RTET and TPS61181RTET. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Ensure that any alternative device meets the same thermal and regulatory requirements as the original specification.
