The Texas Instruments UCC3817DG4 is a BiCMOS Power Factor Preregulator controller designed to achieve near-unity power factor. It shapes the AC input line current waveform to match the AC input line voltage, utilizing average current mode control for stable, low distortion sinusoidal line current. This device operates within a voltage range of 12V to 17V and a frequency range of 6 kHz to 220 kHz.
Key features include over-voltage protection, accurate power limiting, and improved noise immunity. The UCC3817DG4 is suitable for applications such as PC power, consumer electronics, and industrial power supplies. It is housed in a 16-SOIC package and operates at temperatures from 0°C to 70°C.
Designed for efficiency, it offers a low start-up current of 150 µA and low-power BiCMOS operation. The controller supports worldwide line operation and features leading-edge modulation to reduce ripple current in the bulk capacitor. Its average current mode control ensures stable performance across various load conditions.
