TPS923655DMTR

Overview

The TPS923655DMTR is a non-synchronous boost or buck-boost LED driver IC from Texas Instruments. It features an integrated switching FET capable of delivering up to 4 A output current. The device operates with an input voltage range of 4.5 V to 65 V and supports programmable switching frequencies between 100 kHz and 2.2 MHz. It provides an output voltage range of 0 V to 63 V within a VSON-14 package. The component supports analog, flexible, hybrid, and PWM dimming methods. It includes cycle-by-cycle over-current protection, thermal foldback, and thermal shutdown for robust operation.

Feature Summary

• Integrates a high-voltage switching FET for compact design
• Supports multiple dimming methods including PWM and analog
• Includes comprehensive protection mechanisms such as thermal shutdown and open/short detection

Applications

• General LED lighting systems
• Industrial lighting applications
• Automotive exterior lighting modules

Procurement Notes

Verify the specific suffix 'DMTR' against the official datasheet to confirm tape-and-reel packaging and temperature grade. Ensure the application circuit matches the non-synchronous topology requirements. Cross-reference the VSON-14 footprint with PCB layout guidelines provided in the reference manual. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel solution with integrated power switch is required for high-voltage LED strings. It is suitable for designs needing flexible dimming control and wide input voltage compatibility. Consider the thermal performance in the VSON-14 package relative to the expected load current. Evaluate the need for external components versus the integrated protection features offered by this driver.

Part Context

This part belongs to the TPS92365x series of LED drivers designed for versatile lighting applications. It shares functional similarities with the TPS923654MDMTR but may differ in specific ordering suffixes or packaging details. The series targets applications requiring efficient power conversion and reliable LED regulation without complex external gate drive circuits.

Replacement Considerations

The TPS923654MDMTR is a documented alternative within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution. Check if the specific suffix differences impact packaging or qualification standards.
