Description

The IR4007K is a dual mode voltage and current controller combined with a MOSFET in a single Package.

The IR4007K is designed for use in AC/DC and DC/DC switching power supplies upto 100VDC nominal input. The device can operate in either a quasi-resonant or Pulse Ratio Control (PRC) mode, and thereby variable frequency operation.
