Overview
The TPS92075DDC/NOPB is a non-isolated, phase-dimmable buck power factor correction (PFC) LED driver from Texas Instruments. It operates with an input voltage range of 11 V to 18 V and supports switching frequencies between 45 Hz and 64 Hz. The device features integrated digital reference control for precise regulation. It is housed in a compact SOT-23-Thin-6 surface-mount package. The component is designed for high-efficiency lighting applications, offering thermal shutdown protection and soft-start capabilities. It functions within an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrated digital phase-angle decoder for accurate dimming control
- Controlled reference derived power factor correction
- Digital synchronization for 50/60 Hz line frequency
- Phase-symmetry balancing for reduced flicker
Applications
- Non-isolated AC-DC LED lighting systems
- Triac forward phase dimmable fixtures
- PWM reverse phase dimmable luminaires
- High-power density LED drivers
Procurement Notes
Verify the specific suffix 'DDC' corresponds to the SOT-23-Thin-6 package variant rather than the standard SOIC-8 version. Confirm RoHS compliance status and check for recent production lifecycle notices. Ensure the ordering code matches the required tape-and-reel quantity if applicable. Cross-reference the manufacturer's official datasheet to validate pinout compatibility for PCB layout design.
Selection Notes
Select this component for applications requiring non-isolated topologies with integrated PFC functionality. It is suitable for designs needing digital phase-angle decoding without external microcontrollers. Consider the SOT-23-Thin-6 package constraints for space-limited boards. Evaluate thermal performance requirements given the high operating temperature range and potential heat dissipation in enclosed fixtures.
Part Context
This part belongs to the TPS92075 family of LED drivers designed for universal AC input applications. It complements other variants like the TPS92075DR/NOPB, which utilizes an SOIC-8 package. The series focuses on simplifying design through integrated digital controls and phase-symmetry balancing. It targets cost-sensitive and space-constrained lighting solutions requiring high reliability.
Replacement Considerations
The TPS92075DDCR/NOPB serves as a reel-pack alternative to the cut-tape or tube variant. Verify package dimensions and thermal characteristics when substituting with other SOT-23-THIN-6 devices. No direct cross-brand substitutes are confirmed in public documentation.
