The Texas Instruments UCC2818DWTR is an integrated circuit designed for active power factor correction (PFC) preregulators. It utilizes average current mode control to shape the AC input line current waveform, aligning it with the AC input line voltage for near-unity power factor.
This controller operates within a frequency range of 6 kHz to 220 kHz and features a typical start-up current of 150 μA. It supports a wide operating voltage range and is designed for operation between -40°C and 85°C.
The UCC2818DWTR is housed in a 16-SOIC package, suitable for surface mount applications. Its design aims to limit line distortion and provide accurate power limiting, making it suitable for various power supply applications including PC power, consumer electronics, and industrial power supplies.
Key features include over-voltage protection, improved noise immunity, and feed-forward line regulation. The device is built on Texas Instruments' BiCMOS process, offering low power dissipation and improved performance at light load conditions.
