Overview
The TPS75105DSKR is a low dropout, two-bank LED driver IC manufactured by Texas Instruments. It features four constant current channels with an 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 (DSK) and functions across a temperature range of -40°C to +85°C. Key electrical specifications include a maximum power dissipation of 660 mW and a maximum supply current of 300 µA.
Feature Summary
- Integrates two independent LED driver banks for flexible backlight control
- Supports PWM brightness control for precise dimming applications
- Includes thermal shutdown protection for enhanced system reliability
Applications
- Mobile phone LCD backlight systems
- Portable electronic device illumination
- Embedded display lighting solutions
Procurement Notes
Verify the specific suffix 'DSKR' corresponds to the WSON-10 package and tape-and-reel quantity when ordering. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limit. Ensure input voltage constraints are strictly maintained between 2.7 V and 5.5 V to prevent device malfunction or damage during integration.
Selection Notes
Select this component for designs requiring compact surface-mount integration with dual-bank LED control capabilities. The WSON-10 package offers a small footprint suitable for space-constrained portable devices. Consider the 25 mA per channel output capability when determining the number of LEDs driven per bank. Verify compatibility with existing PWM control signals from the host microcontroller.
Part Context
This part belongs to the TPS75105 series of low dropout LED drivers. It is designed specifically for applications requiring efficient linear regulation of LED currents. The DSKR variant denotes the specific tape-and-reel packaging format for automated assembly processes.
Replacement Considerations
The TPS75105DSKT and TPS75105DSKR are functionally equivalent components differing primarily in packaging format. Verify pinout compatibility before substitution. No other direct substitutes are confirmed in the provided documentation.
