TPS92601QPWPRQ1

LED Driver IC Overview

The TPS92601QPWPRQ1 is a single-channel automotive-grade LED driver controller designed for high-side current sensing applications. It supports Boost, Flyback, and SEPIC topologies with an input voltage range of 4V to 40V and output voltages up to 75V. The device operates within a frequency range of 100 kHz to 600 kHz and features PWM dimming capabilities. Packaged in a 20-HTSSOP case, it is AEC-Q100 qualified and rated for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Single-channel high-side current sensing architecture for precise LED control
• Supports multiple DC-DC converter topologies including Boost, Flyback, and SEPIC
• Integrated PWM dimming functionality for brightness adjustment

LED Driver IC Applications

• Automotive headlight systems
• LED lighting driver solutions
• High-side switching mode LED drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'QPWPRQ1' matches the required 20-pin HTSSOP package and automotive grade qualification. Confirm that the single-channel configuration aligns with system requirements, as other variants may offer dual channels or different pinouts. Ensure compatibility with the intended Boost, Flyback, or SEPIC topology before procurement.

LED Driver IC Selection Notes

Select this component when a single-channel solution is sufficient for the application. Consider the TPS92602 series if dual-channel output is required. Verify that the 20-pin HTSSOP package fits the PCB layout constraints. Ensure the operating temperature range meets the environmental demands of the specific automotive zone.

LED Driver IC Part Context

This part belongs to the TPS9260x family of automotive LED drivers from Texas Instruments. It serves as a specialized controller for managing high-side current in LED strings, distinct from multi-channel variants like the TPS92602 which offers two outputs. The QPWRQ1 suffix indicates automotive qualification and specific packaging.

LED Driver IC Replacement Considerations

The TPS92601BQPWPRQ1 is listed as a direct substitute. Verify that the 'B' variant maintains identical electrical characteristics and pinout compatibility for the specific design implementation.
