TPS92074DDCR

Overview

The TPS92074DDCR is a non-isolated, buck Power Factor Correction (PFC) LED driver featuring digital reference control. It operates from an AC/DC input and provides a single output with a maximum current of 2 A. The device supports both analog and PWM dimming methods. It functions within an operating temperature range of -40°C to +125°C. The component is housed in a SOT-23-THN package with six pins.

Feature Summary

• Integrates digital reference control for precise regulation
• Supports combined analog and PWM dimming capabilities
• Designed as a non-isolated buck PFC topology

Applications

• General LED lighting systems
• AC/DC offline switcher implementations
• Surface-mount LED driver designs

Procurement Notes

Verify the specific suffix 'DDCR' against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with the required SOT-23-THN footprint and pinout. Confirm RoHS3 compliance status through the manufacturer's latest datasheet or product change notification records before finalizing procurement specifications.

Selection Notes

Select this component when a non-isolated buck PFC solution is required for LED applications. It is suitable for designs needing integrated digital reference control and dual-mode dimming support. Consider the SOT-23-THN package constraints and the wide operating temperature range for thermal management planning in compact form factors.

Part Context

This part belongs to the TPS92074 series of LED drivers manufactured by Texas Instruments. It is categorized under AC/DC offline switchers and PMIC power management ICs. The device is designed to replace older discrete solutions by integrating PFC and constant current drive functions into a single surface-mount component.

Replacement Considerations

Public confirmed substitute part numbers include TPS92074DDCT and TPS92074D.
