UCC2818ADR Description

Short technical summary and product information.

The Texas Instruments UCC2818ADR is a Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller. It is designed to shape the AC input line current waveform to achieve near-unity power factor and limit line distortion. This device operates within a voltage range of 12V to 17V and supports a frequency range of 6kHz to 220kHz.

 

Key features include average current mode control, overvoltage protection, and accurate power limiting. The controller also offers improved noise immunity and feed-forward line regulation. It has a typical start-up current of 150 µA, making it suitable for low-power applications.

 

The UCC2818ADR is supplied in a 16-pin SOIC package, designed for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. This part is not recommended for new designs.

 

This PFC controller is part of the UCCx81xA family, providing essential functions for active power factor corrected preregulators.
