Overview
The TPS92075D/NOPB is a non-isolated, phase-dimmable buck power factor correction (PFC) LED driver from Texas Instruments. It integrates a hybrid PFC controller with a built-in phase dimming decoder for forward and reverse phase applications. The device supports an input voltage of 18 V and delivers up to 2 A output current. Operating frequencies range from 45 Hz to 65 Hz. It features adjustable switch frequency, soft start, and thermal shutdown protection within an 8-SOIC package.
Feature Summary
- Integrates a hybrid power factor controller with a digital reference control mechanism
- Includes a built-in decoder for forward and reverse phase dimming compatibility
- Provides brightness control and dimming capabilities without external isolation
Applications
- Non-isolated LED lighting fixtures requiring phase dimming
- Buck topology LED drivers with power factor correction
- Commercial and residential general illumination systems
Procurement Notes
Verify the specific suffix 'D' against the manufacturer's official documentation to confirm the package type and tape/reel specifications. Ensure the component matches the required operating temperature range and electrical ratings for the target application before procurement.
Selection Notes
Select this component for designs requiring integrated phase dimming decoding in a non-isolated buck topology. Consider the 8-SOIC package constraints and the 18 V input voltage limit. Evaluate thermal performance given the integrated PFC and dimming functions.
Part Context
This part belongs to the TPS92075 series of LED lighting drivers. It is designed for AC-DC offline switching applications where high power factor and dimmability are critical. The series includes variants with different packaging options to suit various manufacturing requirements.
Replacement Considerations
Check for direct substitutes such as the TPS92075DR/NOPB or TPS92075DDCR/NOPB. Verify pinout compatibility and electrical parameter equivalence before substitution.
FAQ
What types of phase dimming does the TPS92075D/NOPB support?
It supports both forward phase (triac) and reverse phase dimming through its built-in decoder.
Is the TPS92075D/NOPB an isolated driver?
No, it is a non-isolated buck PFC LED driver.
