The UC3854DW from Texas Instruments is an integrated circuit designed for active power factor correction. It controls boost PWM to achieve a power factor of up to 0.99 and limits line-current distortion to less than 5%. This device utilizes average current-mode control for stable, low-distortion current control.
Key electrical specifications include a supply voltage range of 14.5V to 30V, a typical supply current of 1.5mA, and a switching frequency of 200kHz. The operating temperature range is from 0°C to 70°C.
The UC3854DW is housed in a 16-SOIC package, suitable for surface mount applications. Its design facilitates worldwide operation without switches and includes feedforward line regulation.
This component is suitable for applications such as offline AC-to-DC converters, medical, industrial, telecom, and IT power supplies, uninterruptible power supplies (UPS), and appliances.
