The IRIS4007(K) is a dual mode voltage and current controller combined with a MOSFET in a single Package. The IRIS4007(K) are designed for use in AC/DC and DC/DC switching power supplies upto 100VDC nominal input and is capable of 30W for a nominal 48V input. The device can operate in either a quasi-resonant or Pulse Ratio Control (PRC) mode, and thereby variable frequency operation.
