TPS92530QPKDRQ1

LED Driver IC Overview

The TPS92530QPKDRQ1 is an automotive-grade, three-channel constant-current LED driver IC manufactured by Texas Instruments. It features a buck topology with a maximum output voltage of 61 V and supports up to 2 A per channel. The device operates within an input voltage range of 4.5 V to 65 V and offers a programmable switching frequency from 100 kHz to 1.2 MHz. It is housed in a 48-pin HTQFP package and functions reliably across a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Supports analog and PWM dimming for precise light control
• Integrates fault detection and LED open detection capabilities
• Provides thermal error flagging and thermal shutdown protection

LED Driver IC Applications

• Automotive exterior lighting systems
• LED headlamp modules
• Adaptive driving beam applications

LED Driver IC Procurement Notes

Verify the specific suffix QPKDRQ1 against the official Texas Instruments datasheet to confirm the exact package type and tape-and-reel specifications. Ensure that the ordering configuration matches the required automotive qualification standards and that the component meets the intended environmental operating conditions for the target application.

LED Driver IC Selection Notes

Select this component when a three-channel buck converter solution is required for automotive LED arrays. The wide input voltage range accommodates various vehicle power architectures. Consider the integrated thermal management and fault detection features if system reliability and diagnostic feedback are critical design requirements.

LED Driver IC Part Context

This part belongs to the TPS92530-Q1 series of automotive LED drivers. It is distinct from other family members like the TPS925302-Q1, which offers two channels, and the TPS92543-Q1, which utilizes a boost topology. The three-channel architecture makes it suitable for complex lighting configurations requiring independent current regulation.

LED Driver IC Replacement Considerations

Direct substitutes include the TPS92530-Q1 variants with different packaging options. For applications requiring fewer channels, the TPS925302-QPKDRQ1 may serve as a functional alternative. Verify pin compatibility and electrical parameters before swapping with non-automotive grade equivalents.
