UCC3818DW TI Power Factor Correction Controller | 16-SOIC | 0.5A Gate Drive, 6V UVLO

Product Overview

The UCC3818DW from Texas Instruments is a high-performance power factor correction (PFC) controller designed for boost converters operating in continuous conduction mode (CCM). It integrates advanced features to achieve near-unity power factor and low total harmonic distortion (THD) in AC-DC power supplies. The device is housed in a 16-pin SOIC package and operates over a wide supply voltage range from 10V to 21V. With a maximum gate drive current of 0.5A, it can drive external MOSFETs efficiently. The UCC3818DW includes undervoltage lockout (UVLO) with hysteresis, a 1.5% accurate voltage reference, and a programmable switching frequency up to 250 kHz. Its average current mode control ensures stable operation and fast transient response.
