Overview
The TPS92311DR/NOPB is an offline LED driver IC from Texas Instruments, housed in a 16-pin SOIC package. It operates as a primary side sensing controller with integrated power factor correction (PFC). The device supports flyback and buck topologies, delivering up to 2 A output current. Input voltage ranges from 13 V to 35 V, with an adjustable output voltage up to 60 V. Switching frequency is configurable between 60 kHz and 150 kHz. Operating temperature spans -40°C to +125°C.
Feature Summary
- Integrated primary side sensing for simplified transformer design
- Built-in power factor correction functionality
- Supports both flyback and buck converter topologies
- Adjustable switching frequency for optimized efficiency
Applications
- Offline LED lighting drivers
- General illumination systems requiring PFC
- Buck topology LED applications
- Flyback topology LED applications
Procurement Notes
Verify the specific suffix 'DR/NOPB' against the manufacturer's official ordering guide to confirm tape-and-reel packaging and lead-free status. Ensure the component matches the required 16-SOIC package dimensions and thermal characteristics for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.
Selection Notes
Select this component when primary side regulation is preferred over optocoupler-based feedback. It is suitable for designs requiring high power factor without secondary side components. Consider the 16-pin SOIC footprint for assembly constraints. Verify that the input voltage range of 13-35V aligns with your power supply architecture.
Part Context
This part belongs to the TPS9231x family of offline LED drivers. Unlike the TPS92314 which uses an 8-pin package, this variant utilizes a 16-pin SOIC, likely accommodating additional control or sensing pins. It shares core functionalities such as primary side sensing and PFC with other members of the series but differs in physical interface and pinout configuration.
Replacement Considerations
Direct substitutes include TPS92311DR. For similar functionality in different packages, consider TPS92314ADR/NOPB, noting the package change from 16-SOIC to 8-SOIC requires PCB redesign.
