Overview
The TPS92314DR/NOPB is an off-line primary side sensing LED lighting driver controller manufactured by Texas Instruments. It features a flyback topology with natural power factor correction and supports adjustable switching frequencies ranging from 60 kHz to 150 kHz. The device operates within a supply voltage range of 13 V to 35 V, delivering a maximum output current of 2 A. It includes soft switching capabilities and thermal shutdown protection. The component is housed in an 8-SOIC package and functions across an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrates primary side sensing for simplified transformer design without optocouplers
- Provides natural power factor correction to meet regulatory requirements
- Supports analog dimming methods for flexible light control applications
Applications
- Offline LED lighting drivers
- Flyback converter designs
- Buck topology LED applications
Procurement Notes
Verify the specific suffix 'DR/NOPB' against the manufacturer's official documentation to confirm the tape and reel packaging format and lead-free status. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target circuit design. Cross-reference the datasheet revision date to confirm compatibility with current manufacturing standards.
Selection Notes
Select this component for designs requiring primary side regulation to reduce bill of materials cost. Consider the 2 A output current limit when sizing the transformer and output components. Evaluate the 60 kHz to 150 kHz frequency range for EMI filtering requirements. Confirm that the SOIC-8 package fits the available PCB footprint constraints.
Part Context
This device belongs to the TPS92314A series of LED lighting driver ICs. It is designed specifically for offline AC/DC conversion applications where high efficiency and low component count are prioritized. The controller integrates essential protection features to ensure reliable operation in various lighting environments.
Replacement Considerations
The TPS92314DR is a non-NOPB variant of the same base model. Verify pin-to-pin compatibility and electrical equivalence before substitution. No other direct substitute part numbers are confirmed in public documentation.
