Boost CCM PFC for 90W universal input adaptors Evaluation Board

The ISL6730A is an active power factor correction (PFC) controller IC that uses a boost topology. The controller is suitable for AC/DC power systems, up to 2kW and over the universal line input.

The ISL6730A is operated in continuous current mode. Accurate input current shaping is achieved with a current error amplifier. A patent pending breakthrough negative capacitance technology minimizes zero crossing distortion and reduces the magnetic components size. The small external components result in a low cost design without sacrificing performance. The internally clamped 12.5V gate driver delivers 1.5A peak current to the external power MOSFET. The ISL6730A provides a highly reliable system that is fully protected. Protection features include cycle-by-cycle overcurrent, over power limit, over-temperature, input brownout, output overvoltage and undervoltage protection.
