ISL6731A, ISL6731B
Power Factor Correction Controllers
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. The small external components result in lower design cost without sacrificing performance.
The internally clamped 12.5V gate driver delivers 1.5A peak current to the external power MOSFET.
