Overview
The TPS922053DMTR is a 65-V, 2-A buck LED driver with inductive fast dimming and spread spectrum capabilities. It features a wide input voltage range of 4.5 V to 65 V and supports common anode LED connections. The device integrates a 150-mΩ MOSFET capable of delivering continuous output current up to 2 A, with a typical current limit of 3 A. Packaged in a 14-pin VSON (DMT) format measuring 4.5x3 mm, it operates within a temperature range of -40°C to 125°C.
Feature Summary
- Supports inductive fast dimming for high-performance lighting applications
- Integrates spread spectrum functionality to reduce electromagnetic interference
- Features a wide input voltage range suitable for various power supply architectures
Applications
- Automotive exterior lighting systems
- High-brightness general illumination
- Industrial lighting fixtures
Procurement Notes
Verify the specific package marking T2053 against the datasheet to confirm authenticity. Ensure the application circuit matches the 14-pin VSON footprint requirements. Confirm that the input voltage does not exceed the 65-V maximum rating during transient conditions. Check for compatibility with common anode LED configurations as specified in the electrical characteristics.
Selection Notes
Select this component when a 2-A continuous output current is required with integrated power switching. It is suitable for designs needing inductive fast dimming without external components. Consider the thermal performance of the VSON package for high-ambient temperature environments. Verify that the system input voltage falls within the 4.5-V to 65-V operational window.
Part Context
This part belongs to the TPS92205x family of buck LED drivers from Texas Instruments. It shares architectural similarities with the TPS922051 and TPS922055 but differs in output current capability and package type. The DMTR suffix indicates a tape-and-reel packaging option for automated assembly processes.
Replacement Considerations
Direct substitutes include other members of the TPS92205x family such as TPS922051DMTR or TPS922055DMTR, provided the current rating and pinout compatibility are verified. Cross-reference with legacy TI LED driver series if form-factor changes are acceptable.
