TPS61165DRVTG4

Overview

The TPS61165DRVTG4 is a high-brightness white LED driver IC from Texas Instruments, housed in a WSON-6 package. It operates as a boost converter with an input voltage range of 3 V to 18 V and supports up to 1.2 A output current. The device features a 1.2 MHz switching frequency and includes EasyScale 1-Wire interface for brightness control. It provides 38 V open LED protection and maintains a 200 mV reference voltage with 2% accuracy. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Integrates a 1.2 A switch FET with 1.2 MHz switching frequency for efficient power conversion
• Supports flexible single-wire digital and PWM dimming via the EasyScale interface
• Includes load disconnect functionality during shutdown to minimize leakage current
• Features 38 V open LED protection to safeguard against fault conditions

Applications

• High-brightness white LED lighting systems
• Backlight applications requiring precise current regulation
• Portable devices utilizing series-connected LED strings

Procurement Notes

Verify the specific suffix G4 indicates lead-free packaging compliant with RoHS standards. Confirm the WSON-6 package dimensions match your PCB footprint requirements. Ensure the 1.2 A current rating aligns with your LED string configuration. Check that the 3 V to 18 V input range suits your system power supply. Validate thermal performance within the specified -40°C to +85°C operating temperature range.

Selection Notes

Select this component when a compact solution for driving high-brightness LEDs is required. The WSON-6 package offers space efficiency compared to larger alternatives. Consider the 1.2 A limit for LED string sizing and thermal management. The integrated boost topology simplifies design for series LED configurations. Evaluate the EasyScale interface compatibility if digital dimming is necessary for the application.

Part Context

This part belongs to the TPS61165 family of LED drivers designed for high-efficiency operation. The DRVTG4 variant specifically denotes the WSON-6 package with green molding compound. It shares core electrical characteristics with other package options like the SOT-23 version. The family targets portable electronics and general illumination markets.

Replacement Considerations

The TPS61165DRVT serves as a direct functional equivalent but lacks the G4 lead-free suffix. Verify package compatibility between WSON-6 and alternative footprints before substitution. Electrical parameters remain consistent across the base TPS61165 model line.
