Overview
The UCC2818DWTRG4 is a Texas Instruments average current mode power factor preregulator controller. It operates within a switching frequency range of 6 kHz to 220 kHz and supports a supply voltage range of 12 V to 17 V. The device features a low start-up current of 150 µA and is housed in a 16-SOIC package. Designed for surface-mount installation, it functions across an operating temperature range of -40°C to +85°C.
Feature Summary
- Implements average current mode control for high-performance power factor correction
- Provides integrated soft-start functionality to manage inrush currents
- Features low start-up current consumption for efficient power management
Applications
- Offline power factor correction preregulators
- Universal input AC-DC power supplies
- Battery chargers requiring power factor compliance
Procurement Notes
Verify the specific suffix 'DWTRG4' against official documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the component meets RoHS3 requirements as indicated by the manufacturer's specifications. Ensure compatibility with the intended SOIC-16 footprint during procurement planning.
Selection Notes
Select this component when average current mode control is required for power factor correction applications. Consider the 16-SOIC package constraints and the specified operating temperature range. Evaluate the 150 µA start-up current against system power budget requirements before finalizing the design choice.
Part Context
This part belongs to the UCC2818 family of power factor correction controllers from Texas Instruments. It serves as a preregulator solution designed to improve efficiency and reduce harmonic distortion in AC-DC conversion systems. The device integrates essential control loops for stable operation across varying line conditions.
Replacement Considerations
Consult the official datasheet for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter alignment before replacing the component in existing designs.
