Overview
The TPS61165DBVR is a high-brightness white LED driver from Texas Instruments, housed in a SOT-23-6 package. It operates as a boost converter with an integrated 40-V rated switch FET, supporting input voltages from 3 V to 18 V and output voltages up to 38 V. The device delivers a maximum output current of 1.2 A at a switching frequency of 1.2 MHz. It features PWM dimming capability and includes an EasyScale 1-Wire interface for configuration. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrated 40-V rated switch FET for driving series-connected LEDs
- Supports PWM dimming control for brightness adjustment
- Includes EasyScale 1-Wire interface for system configuration
- Provides load disconnect functionality during shutdown mode
Applications
- High-brightness white LED backlighting systems

- Automotive interior lighting applications
Procurement Notes
Verify the specific suffix DBVR corresponds to the SOT-23-6 package variant when sourcing. Confirm that the requested quantity aligns with standard manufacturing packaging constraints. Ensure compatibility with the required operating temperature range and electrical specifications before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a compact solution for driving high-brightness LEDs from a single-cell lithium battery or similar power source. The integrated switch eliminates external inductor requirements, reducing board space. Consider the 1.2-A current limit and 38-V output voltage ceiling to ensure adequate headroom for the target LED string configuration.
Part Context
This part belongs to the TPS61165 family of LED drivers designed for portable and automotive lighting. It shares functional similarities with variants like the TPS61165DRVRG4, which utilizes a WSON-6 package. The family focuses on providing efficient boost conversion with digital control interfaces for modern display and lighting systems.
Replacement Considerations
The TPS61165DRVRG4 serves as a pin-compatible alternative offering the same electrical performance in a WSON-6 package. Designers should verify footprint dimensions and thermal characteristics when substituting between SOT-23-6 and WSON-6 packages.
