TPS922053DRRR

Overview

The TPS922053DRRR is a non-synchronous buck LED driver from Texas Instruments, housed in a WSON-12 package. It supports an input voltage range of 4.5 V to 65 V and delivers up to 2 A output current. The device operates at switching frequencies between 100 kHz and 2.2 MHz, with an output voltage range of 0 V to 63 V. It features integrated cycle-by-cycle over-current protection, thermal foldback, and shutdown capabilities.

Feature Summary

Supports inductive fast dimming for high-performance lighting control
Integrates spread spectrum technology to reduce electromagnetic interference
Includes comprehensive protection mechanisms such as open and short detection

Applications

General LED lighting systems
LED backlighting applications
Industrial illumination setups

Procurement Notes

Verify the specific ordering suffix DRRR to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure compatibility with the required WSON-12 footprint during PCB layout. Cross-reference the datasheet for thermal pad requirements and soldering profiles to guarantee reliable assembly and long-term operational stability.

Selection Notes

Select this component when a single-channel buck topology is required for driving high-power LEDs. It is suitable for designs needing wide input voltage ranges and precise current regulation. Consider the integrated switch and protection features to simplify bill of materials. Evaluate the operating temperature range against environmental constraints.

Part Context

This part belongs to the TPS92205x family of buck LED drivers. It shares functional similarities with models like the TPS922052 but may differ in specific pinout configurations or feature sets. The family is designed for robust LED driving with integrated power switches and advanced dimming capabilities.

Replacement Considerations

The TPS922052DRRR is a documented substitute within the same product family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Review application notes for any design modifications required due to minor functional differences.
