Procurement Notes

Verify the specific revision status and manufacturing origin before procurement. Confirm that the SOIC-8 package variant aligns with the target PCB footprint requirements. Ensure the component meets all necessary regional compliance standards for the intended deployment environment.

Selection Notes

Select this controller for designs requiring integrated PWM control in single-stage topologies. Consider the fixed 100 kHz frequency when designing magnetic components. Evaluate the 800 mA output current limit against the specific LED string requirements to ensure adequate drive capability without exceeding thermal limits.

Part Context

This component belongs to the TPS92001/2 family of general LED lighting PWM controllers. These devices combine control and drive circuitry specifically optimized for cost-effective single-stage AC-DC solutions. The series targets applications where compact design and simplified bill of materials are critical priorities.

Replacement Considerations

The TPS92001DGK serves as a pin-compatible alternative in an 8-VSSOP package. Verify thermal performance differences between the SOIC-8 and VSSOP packages when substituting.
