UCC2817N Bicmos Power Factor Preregulator IC Dip 16

UCC2817N Bicmos Power Factor Preregulator IC Dip 16

The UCC2817N is a high-performance BiCMOS Power Factor Correction (PFC) preregulator controller IC designed to control boost-type PFC circuits in offline power supplies. It enables designers to achieve a near-unity power factor, reduce input current harmonics, and improve overall power efficiency.

This IC uses average current-mode control for precise shaping of the input current and accurate output voltage regulation. It integrates essential control blocks such as an error amplifier, multiplier, and current amplifier, making it ideal for front-end PFC stages in modern switch-mode power supplies (SMPS). The DIP-16 through-hole package makes it easy to use in prototypes and production designs.
