UCC3817N Description

Short technical summary and product information.

The Unitrode UCC3817N is an integrated circuit designed to provide active power factor correction in power supply applications. It achieves near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage.

 

This controller utilizes average current mode control for stable, low-distortion sinusoidal line current. Key electrical specifications include an operating voltage range of 12-V to 17-V and a typical start-up current of 150 µA. It also features improved feed-forward line regulation and leading-edge modulation techniques.

 

The UCC3817N is suitable for various power supply designs requiring efficient power factor correction. Its design focuses on limiting line distortion and enabling world-wide line operation. The component is available in an N package.
