TPS61052DRCT

Overview

The TPS61052DRCT is a high-power white LED driver IC featuring a synchronous boost converter topology with an I2C-compatible interface. It operates within an input voltage range of 2.5 V to 6 V and delivers a maximum output current of 1.2 A. The device supports a fixed switching frequency of 2 MHz and provides a regulated output voltage up to 5.5 V. Packaged in a compact VSON-10 (3x3 mm) footprint, it functions across a temperature range of -40°C to +85°C.

Feature Summary

Integrates an I2C-compatible digital interface for precise control of LED drive current and operational modes.
Employs a synchronous boost converter architecture to maximize energy efficiency during step-up regulation.
Includes a load disconnect mechanism that isolates the output from the load during shutdown states.

Applications

High-power white LED driving in portable electronic devices
Flash lighting systems requiring precise current control
Battery-powered consumer electronics utilizing single LED configurations

Procurement Notes

Verify the specific suffix 'DRC' corresponds to the VSON-10 package variant when sourcing. Confirm the 'T' designation indicates reel packaging if applicable to your assembly process. Ensure compatibility with I2C bus voltage levels used in the target system design.

Selection Notes

Select this component for applications requiring digital control over analog potentiometer methods. The 2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.2 A limit when sizing for high-brightness requirements or parallel LED strings.

Part Context

This part belongs to the TPS61052 series of LED drivers manufactured by Texas Instruments. It is distinct from general-purpose switching regulators like the TPS61026 due to its specialized constant current output and digital interface capabilities tailored for lighting applications.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other TPS61xxx series parts only if they match the VSON-10 package and I2C interface requirements without pinout conflicts.
