Overview
The TPS75105DSKT 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-10 package (10-SON, 2.5x2.5 mm) for surface mount installation. The component functions as a linear regulator with boost and buck topology capabilities. It includes thermal shutdown protection and operates across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated PWM brightness control for precise dimming applications
- Two-bank architecture supporting independent LED channel management
- Built-in thermal shutdown for enhanced operational safety
Applications
- LED lighting systems requiring precise current regulation
- Portable electronic devices utilizing LED indicators or displays
- Battery-powered applications needing efficient power management
Procurement Notes
Verify the specific suffix 'DSKT' corresponds to the WSON-10 package and reel packaging configuration. Confirm that the intended application aligns with the 25 mA output current limit and the 2.7 V to 5.5 V input voltage range. Ensure compatibility with the specified operating temperature range of -40°C to +85°C for the target environment.
Selection Notes
Select this component when a compact, low-power LED driver with integrated PWM dimming is required. The WSON-10 package offers a small footprint suitable for space-constrained designs. Consider the linear topology and associated power dissipation limits when designing for high-efficiency requirements or high ambient temperatures.
Part Context
This part belongs to the TPS75105 series of LED drivers from Texas Instruments. It is designed specifically for driving LEDs in portable and battery-operated devices. The series emphasizes low quiescent current and compact packaging to support modern miniaturization trends in consumer electronics and lighting solutions.
Replacement Considerations
Check for alternative packages such as DSBGA-9 (e.g., TPS75105YFFR) if pinout compatibility allows. Verify functional equivalence regarding output current and control interfaces before substitution.
