UC3854AN Description

Short technical summary and product information.

The UC3854AN from Texas Instruments is an enhanced bipolar CCM PFC controller that provides functions for active power factor corrected preregulators. It achieves near unity power factor by shaping the AC input line current waveform to correspond to the AC input line voltage using average current mode control. This maintains stable, low distortion sinusoidal line current without the need for slope compensation.

 

Key electrical specifications include an operating voltage range of 10V to 20V and a frequency of 200kHz. The device features a high bandwidth of 5 MHz and limits line current distortion to less than 3%. It offers UVLO options of 16V/10V or 10.5V/10V and a low start-up supply current of 300 µA.

 

Designed for through-hole mounting, the UC3854AN comes in a 16-PDIP package. The operating temperature range is 0°C to 70°C. This part is not recommended for new designs, and alternates such as the UCC28180DR are available.
