TPS61196PWPR

Overview

The TPS61196PWPR is a current-mode boost controller designed for driving up to six white LED (WLED) strings. It supports an output voltage of 60V and provides a maximum string current of 400mA. The device features independent PWM dimming control for each individual string, allowing for precise brightness management across multiple segments. Packaged in a PWPR format with a reel quantity of 2000 units, it includes humidity sensitivity indicators and complies with RoHS standards.

Feature Summary

• Current-mode boost controller architecture for efficient LED string driving
• Independent pulse-width modulation dimming capability for each of the six LED strings
• Supports high-output voltage operation up to 60V for series-connected LEDs

Applications

• Backlighting systems for mobile devices requiring multi-segment WLED arrays
• Portable electronic displays utilizing independent zone dimming
• High-brightness lighting modules with complex LED string configurations

Procurement Notes

Verify component authenticity through authorized Texas Instruments channels or certified distributors. Confirm that the specific PWPR suffix matches the required tape-and-reel packaging specifications. Ensure storage conditions account for the indicated moisture sensitivity level to prevent package damage during soldering processes.

Selection Notes

Select this component when designing circuits requiring simultaneous control of multiple LED strings with distinct dimming profiles. Evaluate input voltage ranges against system requirements, noting potential failures if supply drops below 8V. Consider the 60V output limit and 400mA current capacity to ensure compatibility with the target LED array topology.

Part Context

This part belongs to the TPS61196 family of LED drivers manufactured by Texas Instruments. It serves as a specialized solution for applications demanding high-efficiency power conversion alongside granular light control. The device integrates boost regulation with per-string current sensing to maintain consistent luminance across varying thermal and electrical conditions.

Replacement Considerations

Consult official Texas Instruments documentation for verified substitute part numbers within the same product line. Cross-reference pinout and electrical parameters carefully before integrating alternative components to ensure functional equivalence.
