INTEGRATED SWITCHER
Descriptions
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.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are
absolute voltages referenced to terminals stated, all currents are defined positive into any lead. The thermal resistance and
power dissipation ratings are measured under board mounted and still air conditions.
Recommended Operating Conditions
Time for input of quasi resonant signals.
For the Quasi resonant signal inputted to the V
