UCC3818AN Description

Short technical summary and product information.

The UCC3818AN from Unitrode is a BiCMOS Power Factor Preregulator controller designed to achieve near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage. It utilizes Average Current Mode control for stable, low-distortion sinusoidal line current.

 

This controller operates within a voltage range of 12V to 17V and supports a frequency range from 6kHz to 220kHz. Key features include a typical start-up current of 150 µA, overvoltage protection, and Continuous Control Mode (CCM).

 

The UCC3818AN is suitable for applications such as PC power supplies, consumer electronics, lighting, and industrial power supplies, particularly those requiring IEC6100-3-2 compliance for supplies less than 300W.

 

Packaged in a 16-PDIP through-hole configuration, it operates within a temperature range of 0°C to 70°C.
