Evaluation Board For ISL6730D Power Factor Correction Controller

The ISL6730D is 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 ISL6730D operate in Continuous Conduction 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. 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 ISL6730D provide 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. The ISL6730D provide excellent power efficiency and transitions into a power saving skip mode during light load conditions, thus improving efficiency automatically. The ISL6730D switch at 62kHz, switch at 124kHz.
