ISL6731A规格书详情
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. 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, input
brownout, 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 down
by 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.
