Typical Application Notes The UC1852 provides a low-cost active power factor correction (PFC) solution for systems that extract high peak current pulses from AC power lines. The circuit implements a zero-current switching boost conversion, producing a sinusoidal input current with minimal external components, while keeping the peak current much lower than that of a fully discontinuous ...
