Product Details:
The UC3854BDWTR, manufactured by Unitrode, is an integrated circuit designed for power factor correction (PFC) applications utilizing an average current mode control scheme. This device operates at a fixed switching frequency of 120 kHz, facilitating a balance between efficiency and component size. The average current mode control topology ensures a sinusoidal input current waveform, minimizing harmonic distortion and improving power factor. Housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, the UC3854BDWTR is suitable for surface mount assembly. It incorporates internal circuitry for voltage and current loop compensation, over-voltage protection, and soft-start functionality, contributing to a robust and reliable PFC front-end design. The device is optimized for continuous conduction mode (CCM) operation in boost converter topologies, commonly employed in AC-DC power supplies to meet stringent power quality standards.
