TPS61180RTERG4

Overview

The TPS61180RTERG4 is a Texas Instruments LED driver IC featuring six regulated outputs with 25mA current per channel. It utilizes a boost DC-DC converter topology and supports PWM dimming for backlight applications. The device operates within a supply voltage range of 5V to 24V, delivering up to 38V output. Packaged in a 16-WQFN (3x3) exposed pad surface-mount case, it functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates six independent constant-current channels for uniform LED illumination
• Supports high-frequency PWM dimming control for display backlights
• Incorporates internal power switches within a compact WQFN package

Applications

• Mobile device LCD backlights
• Portable electronic display systems
• Consumer electronics lighting modules

Procurement Notes

Verify the specific suffix 'ERG4' against official Texas Instruments documentation to confirm lead-free compliance and RoHS status. Ensure the 16-WQFN thermal pad soldering requirements are met during assembly. Confirm that the 5V minimum supply voltage aligns with the target system design before procurement.

Selection Notes

Select this component when designing multi-channel LED backlight circuits requiring precise current regulation. It is suitable for space-constrained portable devices needing integrated boost conversion. Verify that the 25mA per channel rating meets the specific LED array requirements and that the 38V maximum output voltage accommodates the series string configuration.

Part Context

This part belongs to the TPS6118x family of LED drivers from Texas Instruments. It shares architectural similarities with the TPS61181 and TPS61182 but differs in specific electrical characteristics and pin configurations. The RTERG4 designation indicates a reel-packaged, lead-free version of the standard TPS61180 device.

Replacement Considerations

Public confirmed substitute part numbers: TPS61181RTET, TPS61181RTETG4.
