Offline Controllers/PFC

Analog Devices family of power factor correction (PFC) controllers and offline regulators provide a power factor correction of greater than 0.97, minimize electromagnetic interference to enable compliance with most harmonic current emission requirements, minimize losses in power switch to improve efficiency, and provide a single stage PFC regulator solution with minimal external components. Our power factor correction controllers also contain a temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output state, ideally suited to driving power MOSFETs.
