TPS92200D1RXLR

Overview

The TPS92200D1RXLR is a synchronous buck LED driver IC from Texas Instruments, designed for high-efficiency lighting applications. It features an integrated high-side and low-side NMOS switch architecture, supporting a wide input voltage range of 4 V to 30 V. The device delivers a maximum output current of 1.5 A with adjustable output voltage capabilities. Operating at a fixed switching frequency of 1 MHz, it supports both analog and PWM dimming methods for precise light control. The component is housed in a compact VQFN-HR-6 package, suitable for surface-mount assembly, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates high-side and low-side NMOS switches for efficient synchronous buck topology
• Supports flexible dimming control via analog input signals or pulse-width modulation
• Includes built-in short circuit and thermal protection mechanisms for system reliability

Applications

• General industrial illumination systems
• Commercial lighting fixtures
• High-bay and street lighting drivers

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tape-and-reel specifications match the design requirements. Confirm that the VQFN-HR-6 footprint aligns with the PCB layout guidelines provided in the datasheet. Ensure compliance with RoHS standards and check moisture sensitivity levels for proper storage and handling procedures during assembly.

Selection Notes

Select this component when a compact solution with integrated power switches is required for constant current LED driving. The 1 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.5 A current limit and 30 V input ceiling to ensure adequate headroom for the target LED string configuration and supply voltage variations.

Part Context

This part belongs to the TPS92200 series of LED drivers, which are optimized for single-channel applications. The D1 suffix typically denotes specific internal characteristics or package variants within the family. Evaluation modules such as the TPS92200D1EVM are available to assist in design validation and performance testing before final implementation.

Replacement Considerations

The TPS92200D1DDCR serves as a pin-compatible alternative offering the same electrical specifications but utilizes a SOT-23-6 package instead of the VQFN-HR-6 form factor. Designers must verify thermal performance and PCB trace routing differences when substituting between these package types.
