TPS92515DGQ

LED Driver IC Overview

The TPS92515DGQT is a single-channel LED driver IC from Texas Instruments, utilizing a buck topology with an integrated N-FET. It supports an input voltage range of 5.5 V to 42 V and delivers up to 2 A of constant output current. The device operates at a fixed switching frequency of 2 MHz and features adjustable output voltage. It accommodates analog and PWM dimming control, functions within a temperature range of -40°C to +125°C, and is housed in a 10-pin MSOP-PowerPad package.

LED Driver IC Feature Summary

• Integrates a high-side N-FET switch for compact design
• Supports both analog and pulse-width modulation (PWM) dimming methods
• Includes thermal shutdown protection for enhanced reliability

LED Driver IC Applications

• LED lighting systems
• General illumination applications

LED Driver IC Procurement Notes

Verify the specific suffix against official documentation, as 'DGQ' may denote a variant distinct from the standard 'DGQT' or 'DGQR' packages. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the ordering part number matches the exact package type and tape/reel specifications required for the manufacturing process.

LED Driver IC Selection Notes

Select this component for designs requiring a fixed 2 MHz switching frequency and a maximum 2 A output current. It is suitable for applications where a 5.5 V minimum input voltage is acceptable. Consider alternative models if lower input voltage operation or higher current capacity is necessary for the specific system requirements.

LED Driver IC Part Context

This device belongs to the TPS92515 series of LED drivers. It shares functional similarities with other members of the family but is distinguished by its specific 2 A current rating and 2 MHz operating frequency. It serves as a dedicated solution for driving single-channel LED loads in automotive and industrial environments.

LED Driver IC Replacement Considerations

The TPS92515DGQR is a reel-packaged equivalent of the cut-tape DGQT variant. Other series members like the TPS92512 offer different current ratings and frequency ranges.
