Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and pin alignment against the 8-VSSOP specification. Check for RoHS3 compliance documentation. Ensure storage conditions respect the moisture sensitivity level classification. Validate that the specific revision matches design requirements before integration.

Selection Notes

Select this controller for applications requiring a general-purpose PWM solution with integrated drive circuitry. It is suitable for designs utilizing flyback or buck topologies where Triac dimming is necessary. Consider the 100kHz switching frequency and 21V max supply voltage when designing the power stage. Ensure the thermal environment stays within the specified -40°C to 105°C junction temperature range for reliable operation.

Part Context

The TPS92001DGK belongs to the TPS92001/2 family of general LED lighting PWM controllers. This series provides essential control and drive functions for single-stage AC-DC offline switchers. The DGK suffix indicates the specific 8-VSSOP packaging variant. It is engineered to simplify LED driver design by integrating necessary control logic into a compact surface-mount package.

Replacement Considerations

The datasheet references the TPS92002 as a related family member. Verify if the TPS92002 offers compatible pinouts and electrical characteristics for direct substitution. Consult the official product change notice for any recommended alternatives due to the obsolete status.
