TPS922050D2DSGR

Overview

The TPS922050D2DSGR is a single-channel buck LED driver IC from Texas Instruments, designed for high-efficiency lighting applications. It supports an input voltage range of 4.5 V to 60 V and delivers a maximum output current of 1 A. The device operates at a switching frequency of 400 kHz and features analog or PWM dimming capabilities. Packaged in an 8-pin WSON (2x2 mm) format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Supports both analog and pulse-width modulation (PWM) dimming methods for precise light control.
• Integrates a synchronous buck topology for efficient power conversion in compact designs.
• Includes built-in protection mechanisms against short circuits and thermal overload conditions.

Applications

• General industrial illumination systems
• Commercial lighting fixtures
• Automotive interior lighting modules

Procurement Notes

Verify the specific ordering suffix D2DSGR to ensure the correct package type and tape-and-reel configuration. Confirm that the application requires a 65V rated component with 1A continuous current capability. Cross-reference the datasheet for pinout compatibility if replacing existing designs. Ensure supply chain sources provide authentic Texas Instruments components to guarantee performance reliability.

Selection Notes

Select this component when designing LED drivers requiring wide input voltage ranges up to 60V. It is suitable for space-constrained applications due to its small WSON footprint. Choose over higher-current variants if the load demands exactly 1A. Consider the operating temperature range requirements before finalizing the design.

Part Context

This part belongs to the TPS922050 family of LED drivers, which are optimized for general lighting and automotive uses. It complements other devices like the TPS92200 series but offers higher voltage tolerance. The D2DSGR designation specifies the specific package and packaging method for surface-mount assembly.

Replacement Considerations

Direct substitutes include the TPS922050D1DRLR, which shares similar electrical characteristics but utilizes a different SOT-583-8 package. Designers must verify footprint compatibility and reflow soldering profiles when transitioning between these package types.
