TPS61165DRVR

Overview

The TPS61165DRVR is a high-brightness white LED driver IC manufactured by Texas Instruments, housed in a WSON-6 package. It utilizes a boost topology to drive LEDs in series, featuring an integrated 40-V rated switch FET. The device operates with an input voltage range of 3 V to 18 V and provides an output voltage range of 3 V to 38 V. It supports a maximum output current of 1.2 A and functions at a switching frequency of 1.2 MHz. The component is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 40-V rated power switch FET for efficient boost conversion
• Features EasyScale 1-Wire interface for digital brightness control
• Includes load disconnect functionality during shutdown mode

Applications

• High brightness white LED lighting systems
• Portable electronic devices requiring LED illumination
• General LED backlighting applications

Procurement Notes

Verify the specific package type and marking code on the physical component against the official datasheet specifications. Ensure that the ordering suffix matches the required tape and reel configuration. Confirm RoHS compliance status through the manufacturer's documentation prior to integration into production assemblies.

Selection Notes

Select this component when a compact solution for driving series-connected white LEDs is required. The integrated FET and small WSON-6 footprint make it suitable for space-constrained designs. Consider the 1.2 A current limit and 38 V output ceiling to ensure compatibility with the target LED string configuration.

Part Context

This part belongs to the TPS61165 family of LED drivers from Texas Instruments. It is functionally similar to the TPS61165DBVR but differs in packaging, utilizing a WSON-6 form factor instead of the SOT-23-6 package found in other variants within the same product line.

Replacement Considerations

The TPS61165DBVR serves as a pin-compatible alternative within the same family, offering identical electrical performance but packaged in SOT-23-6. Verify package dimensions and thermal characteristics when substituting between these two variants.
