TPS92518HVPWPR

LED Driver IC Overview

The TPS92518HVPWPR is a dual buck LED controller from Texas Instruments, designed for high-voltage LED lighting applications. It operates with an input voltage range of 6.5 V to 65 V and supports two independent constant current outputs, each capable of delivering up to 5 A. The device features adjustable switching frequencies ranging from 1 kHz to 2 MHz and includes SPI interface capabilities for configuration. It is housed in a 24-pin HTSSOP package and functions within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Dual independent buck channels provide precise constant current regulation for complex LED arrays.
• Integrated SPI interface enables digital control and monitoring of driver parameters.
• Supports both analog and PWM dimming methods for flexible brightness control.
• Includes thermal shutdown protection to ensure operational safety under fault conditions.

LED Driver IC Applications

• Automotive exterior lighting systems
• High-power LED general illumination fixtures
• Industrial lighting applications requiring high voltage inputs

LED Driver IC Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 65 V maximum input rating aligns with your system's supply voltage headroom. Ensure compatibility with the 24-pin HTSSOP footprint during PCB layout. Check for moisture sensitivity level requirements if storage conditions exceed specified limits.

LED Driver IC Selection Notes

Select this component when designing circuits that require dual-channel control with high input voltage tolerance. It is suitable for applications needing digital configuration via SPI rather than purely analog setups. Consider the thermal performance of the HTSSOP package relative to your expected power dissipation. Evaluate whether the 5 A per channel output current meets the load requirements of your LED strings.

LED Driver IC Part Context

This part belongs to the TPS92518 family of dual buck LED controllers. The HV variant specifically extends the input voltage capability to 65 V compared to standard versions. It shares core architecture with other members but is optimized for higher voltage automotive and industrial environments. The PWPR suffix indicates the specific reel packaging type used by distributors.

LED Driver IC Replacement Considerations
