The UC3854BDWTR is a high-power factor correction (PFC) integrated circuit designed for use in offline AC-to-DC converters and various power supply applications, including medical, industrial, telecom, and uninterruptible power supplies. It features average current-mode control, enabling fixed-frequency operation with minimal line-current distortion and high stability. The device supports a power factor of up to 0.99 and limits line-current distortion to less than 5%. It operates effectively across a wide input voltage range of 75V to 275V and line frequencies from 50Hz to 400Hz. The UC3854BDWTR includes several integrated functions such as a voltage amplifier, an analog multiplier and divider, a current amplifier, and a fixed-frequency PWM driver. It also features a 1-A totem-pole gate driver, a precision voltage reference, and low startup supply current, making it suitable for high-efficiency designs. The device is available in multiple package options, including 16-pin SOIC, CDIP, and PDIP, facilitating easy integration into various circuit layouts.
