Overview
The TPS92010DR is a high-efficiency offline LED lighting driver controller manufactured by Texas Instruments. It utilizes a flyback topology to drive a single output channel with a maximum current of 1 A. The device operates within an input voltage range of 13 V to 21 V and supports an adjustable switching frequency between 40 kHz and 130 kHz. It features analog dimming capabilities and includes soft-start functionality. The component is housed in an 8-SOIC package and is rated for operation at temperatures ranging from -40°C to +105°C.
Feature Summary
- Supports flyback topology for efficient offline LED power conversion
- Enables analog dimming control for light intensity adjustment
- Integrates internal soft-start mechanism to manage inrush current
Applications
- TRIAC dimmable light bulb replacements
- Offline AC-DC LED lighting systems
- General illumination applications requiring high efficiency
Procurement Notes
Verify the specific ordering suffix to ensure the correct tape-and-reel packaging configuration matches your assembly requirements. Confirm that the SOIC-8 footprint aligns with your PCB design guidelines. Cross-reference the datasheet revision history to ensure compatibility with your intended thermal and electrical operating conditions before finalizing procurement.
Selection Notes
Select this component for applications requiring a single-channel flyback converter with integrated dimming control. Ensure the input voltage range of 13 V to 21 V suits your power supply architecture. Consider the 1 A output current limit when designing the transformer and LED string configuration. Verify that the operating temperature range meets the environmental constraints of the target enclosure.
Part Context
This part belongs to the TrueDrive series of LED drivers from Texas Instruments, designed specifically for high-efficiency offline applications. It is distinct from other TPS920xx variants which may offer different topologies such as boost or buck, or support multiple output channels. The TPS92010DR is optimized for cost-effective, compact lighting solutions using standard flyback architectures.
Replacement Considerations
Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative TPS920xx series devices based on topology (flyback) and current rating (1A). Verify pinout compatibility and control interface similarities before considering any cross-model replacement.
