UC3853N TI Power Factor Correction Controller | 8-PDIP | 12V Supply, 0.5A Gate Drive

Product Overview

The UC3853N is a high-performance power factor correction (PFC) controller from Texas Instruments, designed for active power factor correction in AC-DC power supplies. It operates in average current mode control with a fixed frequency of up to 200 kHz. The device integrates a 0.5A gate driver, undervoltage lockout (UVLO), overvoltage protection, and a 1.5% accurate voltage reference. Housed in an 8-pin PDIP package, it is ideal for cost-sensitive applications requiring high power factor and low total harmonic distortion (THD).
