Overview
The TPS92314AD/NOPB is an off-line primary side sensing controller with integrated power factor correction, designed for LED lighting applications. It operates within a supply voltage range of 13 V to 35 V and supports a maximum output current of 2 A. The device features an adjustable switching frequency between 60 kHz and 150 kHz and delivers an adjustable output voltage up to 60 V. It utilizes a flyback topology and is housed in an 8-SOIC package, functioning reliably across a temperature range of -40 °C to +125 °C.
Feature Summary
- Integrates natural power factor correction for improved efficiency
- Supports analog dimming methods for flexible control
- Includes thermal shutdown protection for enhanced reliability
Applications
- LED lighting driver designs
- Offline power supply circuits
- Primary side sensing regulation systems
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm that the 'AD' variant corresponds to the specified SOIC-8 package and operating temperature range. Ensure compatibility with the required flyback transformer design parameters before procurement.
Selection Notes
Select this component for applications requiring integrated PFC and primary side regulation without optocouplers. Consider the 8-SOIC package constraints and the 2 A output limit when designing the thermal management system. Validate that the input voltage range aligns with the target AC/DC source specifications.
Part Context
This part belongs to the TPS92314A series of LED drivers from Texas Instruments. It is engineered for high-efficiency offline applications, combining control logic with power factor correction capabilities. The device simplifies design by eliminating the need for secondary side feedback components.
Replacement Considerations
Consult official Texas Instruments documentation for direct pin-to-pin replacements or functional equivalents within the same family. Verify parameter compatibility for any substitute parts.
