Overview
The TPS92074DR is a non-isolated, buck power factor correction (PFC) LED driver IC from Texas Instruments. It integrates a hybrid PFC controller optimized for driving LED lighting applications. The device operates with an input voltage range of 11 V to 18 V and delivers a maximum output current of 2 A. It features digital reference control for precise regulation. The component is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrates a hybrid power factor correction controller optimized for LED lighting loads
- Utilizes controlled reference derived PFC technology for efficient power management
- Supports digital reference control for accurate output regulation
Applications
- Non-isolated AC/DC LED lighting systems
- Buck topology LED drivers requiring power factor correction
- General illumination applications using single-output LED strings
Procurement Notes
Verify the specific suffix DR indicates the tape-and-reel packaging configuration when ordering. Confirm that the NOPB designation is not required if lead-free compliance is explicitly stated in the final datasheet revision. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before procurement.
Selection Notes
Select this component for designs requiring integrated PFC in a non-isolated buck topology. It is suitable for applications needing up to 2 A output current within a 11 V to 18 V input window. Consider the thermal performance of the SOIC-8 package under full load conditions. Verify compatibility with the intended LED string voltage and current requirements against the device's adjustable limits.
Part Context
This part belongs to the TPS9207x family of non-isolated LED drivers. It shares functional similarities with the TPS92075 but offers different current capabilities and feature sets tailored for specific lighting architectures. The series focuses on simplifying design by integrating PFC and LED drive functions into a single chip.
Replacement Considerations
The TPS92074D is the same device without the reel suffix. Check for TPS92075 variants if higher current or additional dimming features are needed. Verify pinout compatibility before substituting with other TI LED drivers.
