TPS92002DGK

Overview

The TPS92002DGK is a general-purpose PWM controller IC designed for LED lighting applications. It operates as an AC/DC offline switcher supporting flyback and step-down topologies. The device features triac dimming capability and includes a 15V turn-on threshold. It is housed in an 8-VSSOP package and functions within a temperature range of -40°C to 105°C TJ.

Feature Summary

• General-purpose PWM control architecture for LED drivers
• Integrated triac dimming functionality
• Supports flyback and buck converter topologies
• 15V turn-on threshold design

Applications

• LED lighting systems
• AC/DC offline switcher designs
• Triac dimmable lamp applications

Procurement Notes

Verify component status carefully, as the TPS92002DGK may be listed as obsolete or end-of-life by Texas Instruments. Confirm availability through authorized distributors and check for valid production lot dates. Ensure that the specific 8-VSSOP package variant matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring simple PWM control with triac dimming support. It is suitable for flyback or buck topologies where a 15V turn-on threshold is appropriate. Consider the 8-VSSOP package size and operating temperature range when designing for space-constrained or high-thermal environments.
