## Description

The Texas Instruments UCC2818D is a BiCMOS Power Factor Preregulator controller designed for active power factor correction. It controls a boost preregulator to achieve near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage.

Key electrical specifications include an operating frequency range of 6 kHz to 220 kHz, a typical start-up current of 150 μA, and an operating voltage with UVLO (Under-Voltage Lockout) at 10.5V/10V for the UCC2818. It also features a nominal reference voltage of 7.5V and can operate up to 18V.

This controller is suitable for applications such as PC power, consumer electronics, lighting, and industrial power supplies, particularly for IEC6100-3-2 compliant supplies less than 300W. The device is available in a 16-pin SOIC package.

Features include over-voltage protection, accurate power limiting, average current mode control, improved noise immunity, and improved feed-forward line regulation. It utilizes leading-edge modulation to reduce ripple current in the bulk capacitor.
