UC3852N TI Power Factor Correction Controller | 8-PDIP | 16V Supply, 1A Gate Drive

Product Overview

The UC3852N is a high-performance power factor correction (PFC) controller from Texas Instruments, designed to achieve near-unity power factor in offline power supplies. Housed in an 8-pin PDIP package, this device integrates a voltage-mode PWM controller with a multiplier and a zero-crossing detector to shape the input current waveform. It operates from a supply voltage of 16V and provides a 1A gate drive output, making it suitable for boost PFC converters up to several hundred watts. The UC3852N is optimized for low total harmonic distortion (THD) and high efficiency, meeting IEC 61000-3-2 standards.
