The UCC2818DTR from Texas Instruments is a BiCMOS Power Factor Preregulator (PFC) controller. It is designed to control a boost preregulator, achieving near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage. This results in stable, low distortion sinusoidal line current.
Key electrical specifications include an operating frequency range of 6 kHz to 220 kHz, an Under-Voltage Lockout (UVLO) of 10.5V/10V, and a nominal reference voltage of 7.5V. The device also features a typical start-up current of 150 μA and can operate up to 18V.
This PFC controller is suitable for applications such as PC power supplies, consumer electronics, lighting, and industrial power supplies. It is particularly useful for IEC6100-3-2 compliant supplies less than 300W. The UCC2818DTR is available in a 16-SOIC package and is supplied on tape and reel.
Designed with average current mode control, the UCC2818DTR offers features like over-voltage protection, accurate power limiting, and improved noise immunity. Its leading-edge modulation technique helps reduce ripple current in the bulk capacitor.
The operating frequency range is 6 kHz to 220 kHz.
The typical start-up current is 150 μA.
