UCC2818ANG4 TI PFC Controller | 16-PDIP | 250kHz, 12V/10mA Gate Drive

Product Overview

The UCC2818ANG4 is a high-performance power factor correction (PFC) controller from Texas Instruments, designed for boost PFC applications requiring low total harmonic distortion (THD) and high efficiency. It operates in continuous conduction mode (CCM) with average current control, providing a stable and precise output voltage regulation. The device integrates a 250kHz oscillator, a 1.5A peak gate drive, and comprehensive protection features including overvoltage, undervoltage lockout, and cycle-by-cycle current limiting. Housed in a 16-pin PDIP package, it is suitable for industrial and consumer power supplies up to several kilowatts.
