The UCC2819AD is a BiCMOS integrated circuit designed for active power factor corrected preregulators. It achieves near unity power factor by shaping the AC input line current waveform to match the AC input line voltage. This controller utilizes average current mode control to maintain stable, low distortion sinusoidal line current.
Key electrical specifications include an operating voltage range of 10.8V to 17V, a switching frequency of 250kHz, and a typical startup current of 150µA. The device operates within an industrial temperature range of -40°C to 85°C.
Packaged in a 16-SOIC surface mount configuration, the UCC2819AD is suitable for various power supply applications requiring efficient power factor correction. Its design focuses on providing accurate power limiting and improved feed-forward line regulation.
The UCC2819AD offers features such as over-voltage protection and programmable output voltage capabilities, making it a versatile component for power management solutions.
