TPS92200D2RXLR

Overview

The TPS92200D2RXLR is a synchronous buck LED driver from Texas Instruments, designed for high-efficiency lighting applications. It features an input voltage range of 4 V to 30 V and delivers a maximum output current of 1.5 A. The device integrates high-side and low-side NMOS switches to minimize external component count. It supports analog dimming and operates at a switching frequency of 1 MHz. The unit is housed in a VQFN-6-HR package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates high-side and low-side NMOS switches for efficient synchronous buck operation
• Supports analog dimming control for precise brightness adjustment
• Includes short circuit and thermal protection mechanisms

Applications

• General industrial illumination systems
• Commercial lighting fixtures
• High-bay LED lighting solutions

Procurement Notes

Verify the specific suffix 'RXLR' corresponds to the VQFN-6-HR packaging configuration as documented in official Texas Instruments datasheets. Ensure compatibility with the required PCB footprint and thermal management requirements for the selected application environment. Confirm that the analog dimming interface aligns with the system control architecture before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact, single-channel LED driver with integrated power switches. The 1.5 A output capability suits moderate-power LED strings. Consider the 1 MHz switching frequency for trade-offs between component size and electromagnetic interference. Validate that the 30 V maximum input voltage meets the supply rail specifications of the target design.
