TPS60251RTWT

Overview

The TPS60251RTWT is a high-efficiency charge pump LED driver IC manufactured by Texas Instruments. It features seven independent current-controlled outputs, each capable of delivering up to 230 mA. The device operates within an input voltage range of 3 V to 6 V and provides a maximum output voltage of 6.5 V. It utilizes I2C control for configuration and includes soft-start functionality to limit inrush current. The component supports open LED detection and operates at a switching frequency of 750 kHz. It is housed in a WQFN-16 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Seven independent current-mode outputs for precise LED channel control
• I2C interface for digital configuration and monitoring
• Integrated soft-start mechanism to manage power-up transients
• Built-in diagnostic capability for detecting open LED conditions

Applications

• High-efficiency LED lighting systems
• Portable electronic display backlighting
• Multi-channel LED indicator arrays
• Battery-powered illumination devices

Procurement Notes

Verify the specific suffix RTWT against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with I2C bus requirements and thermal management needs for the WQFN-16 footprint. Cross-reference environmental compliance data such as RoHS status directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component when multiple independent LED channels require precise current regulation from a single supply source. The integrated charge pump topology eliminates the need for external inductors, simplifying PCB layout. Consider the 750 kHz switching frequency for EMI constraints and the I2C interface for system-level control flexibility compared to fixed-function drivers.

Part Context

The TPS60251 belongs to the TPS60250 series of LED lighting driver ICs. This family focuses on high-efficiency power conversion for portable applications. The RTWT designation indicates a specific reel-based packaging format suitable for automated surface-mount assembly processes.
