Overview
The UCC38051DR is a transition mode power factor correction (PFC) controller manufactured by Texas Instruments. It operates within a supply voltage range of 12V to 18V and features a startup current of 75 µA. The device supports switching frequencies up to 200kHz and is housed in an 8-SOIC surface-mount package with a width of 3.90mm. Designed for low to medium power applications, it ensures compliance with IEC1000-3-2 standards.
Feature Summary
- Implements transition mode control for efficient power factor correction
- Optimized for low to medium power applications meeting IEC1000-3-2 requirements
- Features low startup current for reduced standby power consumption
Applications
- Low to medium power AC-DC power supplies
- Power factor correction stages in consumer electronics
- Compliance-critical power adapters
Procurement Notes
Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing. Confirm the component status as discontinued or active through authorized distributors, as availability may be limited. Ensure the operating temperature range of 0°C to 70°C aligns with your system design requirements before finalizing procurement.
Selection Notes
Select this component for designs requiring transition mode PFC control in compact surface-mount layouts. It is suitable for applications needing IEC1000-3-2 compliance without complex digital control. Consider the 8-SOIC package constraints and the 200kHz frequency limit when designing magnetic components.
Part Context
This part belongs to the UCC3805x family of transition mode PFC controllers from Texas Instruments. It shares functional similarities with the UCC38051D but differs in packaging. The family is designed to simplify PFC implementation in standard offline power conversion topologies.
Replacement Considerations
The UCC38051D is a pin-compatible alternative in a DIP package. Verify if the SOIC footprint is mandatory for your assembly process. No other direct substitutes are confirmed in the provided documentation.
