The Texas Instruments UC2854DWTR is a high-power factor preregulator IC that provides active power factor correction for power systems. It is designed to draw sinusoidal current from sinusoidal power lines, minimizing line-current distortion to less than 5% and achieving a power factor up to 0.99.
This device utilizes average current-mode control for stable, fixed-frequency PWM operation at 200kHz. It features a wide operating voltage range of 14.5V to 30V and a supply current of 1.5 mA. The UC2854DWTR includes a 1-A totem-pole gate driver and a precision voltage reference.
Packaged in a 16-SOIC surface-mount form factor, the UC2854DWTR is suitable for applications such as offline AC-to-DC converters, medical, industrial, telecom, and IT power supplies, uninterruptible power supplies (UPS), appliances, and white goods. It operates within an ambient temperature range of -40°C to 85°C.
