TPS75100DSKT

Overview

The TPS75100DSKT is a low dropout, two-bank LED driver IC manufactured by Texas Instruments. It features four constant current outputs with a maximum output current of 25 mA per channel. The device operates within an input voltage range of 2.7 V to 5.5 V and supports adjustable output voltages. It utilizes a WSON (DSK) package with 10 pins, specifically a 10-SON (2.5x2.5) configuration. The component supports PWM brightness control and includes thermal shutdown protection. It functions as a linear regulator with boost and buck topology capabilities.

Feature Summary

• Integrates two independent LED driver banks for flexible lighting control
• Supports PWM dimming for precise brightness adjustment
• Includes thermal shutdown protection for enhanced reliability

Applications

• LED backlighting systems
• General LED illumination modules
• Portable electronic display lighting

Procurement Notes

Verify the specific package variant and suffix when sourcing, as the DSKT designation indicates a specific tape-and-reel packaging format. Confirm that the required output current and voltage ranges align with the target LED load specifications. Ensure compatibility with the intended PCB footprint for the 10-SON package. Cross-reference the manufacturer's latest documentation to confirm pinout and electrical characteristics match the design requirements.

Selection Notes

Select this component for applications requiring multi-channel LED driving with integrated dimming capabilities. The dual-bank architecture allows for independent control of LED groups. Consider the low quiescent current and wide input voltage range for battery-powered or variable supply environments. Evaluate the thermal performance and package size constraints against the available board space.
