TPS61160DRVTG4

Overview

The TPS61160DRVTG4 is a white LED driver IC manufactured by Texas Instruments, designed for backlight applications. It features a step-up (boost) DC-DC regulator topology with one output channel capable of delivering up to 700mA switch current. The device supports PWM dimming and operates within an input voltage range suitable for single-cell lithium-ion batteries, reaching a maximum output voltage of 26V. It functions at a switching frequency of 600kHz and is housed in a compact 6-WSON (2x2mm) package with an exposed pad, rated for operation between -40°C and 85°C.

Feature Summary

• Integrated boost converter architecture optimized for driving white LEDs
• Supports digital and PWM brightness control mechanisms
• Compact surface-mount packaging facilitates space-constrained designs

Applications

• Mobile phone backlighting
• Portable electronic device illumination
• General LED lighting systems

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm compliance with RoHS standards and lead-free specifications. Ensure that the ordering part number matches the exact package type and temperature rating required for the target application environment. Cross-reference datasheet revisions to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high efficiency for single-cell battery-powered LED backlights. Consider the 600kHz switching frequency for balancing EMI performance and external component size. Evaluate the thermal dissipation requirements associated with the WSON package if operating near maximum current limits. Confirm that the system's input voltage profile aligns with the device's operational range for optimal regulation.

Part Context

This part belongs to the TPS61160 family of LED drivers from Texas Instruments. It shares functional similarities with other models in the series but is distinguished by its specific package configuration and regulatory compliance markings indicated by the G4 suffix. It serves as a specialized solution for portable electronics where size and power efficiency are critical design constraints.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the TPS61160DRVR or TPS61160ADRV variants. Verify that alternative components match the required output current, package dimensions, and control interface specifications before implementation.
