TPS92075DR/NOPB

Overview

The TPS92075DR/NOPB is a non-isolated, phase-dimmable buck PFC LED driver with digital reference control. It operates from an AC input voltage range of 18 V to 264 V and supports frequencies between 45 Hz and 65 Hz. The device features a built-in triac dimming decoder and adjustable switching frequency. It is housed in an 8-SOIC package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a hybrid power factor controller with a built-in phase dimming decoder for seamless compatibility with leading-edge and trailing-edge dimmers.
Utilizes controlled reference derived PFC technology to maintain high power factor across the dimming range.
Includes protection mechanisms such as thermal shutdown and soft start functionality.

Applications

Non-isolated LED lighting fixtures
Phase-dimmable general illumination systems
Buck PFC LED driver designs

Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing. Confirm that the 'NOPB' designation ensures lead-free manufacturing compliance. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision status before procurement.

Selection Notes

Select this component for applications requiring integrated PFC and dimming capabilities without isolation barriers. Ensure the design accommodates the 8-SOIC thermal requirements. Verify that the load current does not exceed the internal switch limits defined in the electrical characteristics table of the datasheet.

Part Context

This part belongs to the TPS9207x family of LED drivers designed for cost-effective, high-performance lighting solutions. It combines power factor correction and LED driving in a single chip, reducing component count compared to discrete solutions.
