TPS922053DYYR

Overview

The TPS922053DYYR is a 65-V, 2-A buck LED driver from Texas Instruments featuring inductive fast dimming and spread spectrum capabilities. It operates with an 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 handling typical 3-A/6-A current limits for continuous output currents up to 2 A. It utilizes a 14-pin SOT-23-THIN package.

Feature Summary

• Supports inductive fast dimming for high-performance lighting control
• Integrates spread spectrum technology to reduce electromagnetic interference
• Features a wide input voltage range suitable for various power sources
• Includes an integrated low-on-resistance MOSFET for efficient power conversion

Applications

• General LED lighting systems requiring fast dimming
• Automotive exterior lighting applications
• Industrial LED illumination setups
• High-efficiency DC-DC regulated LED drivers

Procurement Notes

Verify the specific suffix DYYR corresponds to the tape-and-reel packaging configuration as defined by Texas Instruments. Confirm that the 2-A output current rating aligns with your thermal management design constraints. Ensure compatibility with common anode LED architectures before procurement. Cross-reference the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions.

Selection Notes

Select this component when a 2-A continuous output current is required alongside inductive fast dimming functionality. It is suitable for designs needing spread spectrum features to minimize EMI without external filtering components. Consider the 14-pin SOT-23-THIN package for space-constrained PCB layouts. Verify that the system input voltage remains within the 4.5-V to 65-V operational window.

Part Context

This part belongs to the TPS92205x family of buck LED drivers, which also includes variants like the TPS922050 and TPS922051. These devices share similar architectural foundations but differ in output current capabilities and specific feature sets such as dimming methods. The TPS922053 specifically targets applications requiring higher current density compared to the 1-A variants in the series.

Replacement Considerations

Direct substitutes within the same family include the TPS922050D1DRLR for lower current requirements or the TPS922053DYYR itself if sourcing from different distributors. Check pin-to-pin compatibility and thermal performance when replacing with other buck LED drivers from Texas Instruments or competitors.
