The ISL6731A and ISL6731B are active power factor correction (PFC) controller ICs that use a boost topology. The controllers are suitable for AC/DC power systems up to 2kW and over the universal line input.The ISL6731A and ISL6731B operate in Continuous Current Mode (CCM). 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. Thesmall external components result in lower design cost without sacrificing performance. The internally clamped 12.5V gate driver delivers 1.5A peakcurrent to the external power MOSFET. The ISL6731A and ISL6731B provide a highly reliable system that is fully protected. Protection features include cycle-by-cycle overcurrent, over-power limit, over-temperature, inputbrownout, output overvoltage and undervoltage protection. The ISL6731A and ISL6731B provide excellent power efficiency and transitions into a power saving skip mode during light load conditions, thus improving efficiency automatically. The ISL6731A and ISL6731B can be shut downby pulling the FB pin below 0.5V or grounding the BO pin.Two switching frequency options are provided. The ISL6731B switches at 62kHz, and the ISL6731A switches at 124kHz.
