The UC3854BN from Texas Instruments is an enhanced bipolar CCM PFC controller that provides active power factor correction. It is designed to shape the AC input line current waveform to correspond to the AC input line voltage, achieving near unity power factor. This controller utilizes average current mode control, which 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 fixed operating frequency of 200kHz. The device draws a low start-up supply current of 300 µA and has an operating current of 250 µA. The operating temperature range is from 0°C to 70°C.
The UC3854BN is housed in a 16-DIP (0.300", 7.62mm) through-hole package. It is suitable for applications requiring high power factor correction and low line current distortion.
This part is not recommended for new designs. Consider alternatives like the UCC28180DR.
