UC2854N TI Power Factor Correction IC | 16-PDIP | 0-95% Duty Cycle, 1MHz

Product Overview

The UC2854N from Texas Instruments is a high-performance power factor correction (PFC) controller designed for offline power supplies. It operates in continuous conduction mode (CCM) and provides near-unity power factor with low harmonic distortion. The device integrates a voltage amplifier, current amplifier, multiplier, and PWM comparator in a single 16-pin PDIP package.
