INTEGRATED SWITCHER
Descriptions
The IRIS4013(K) is a dual mode voltage and current controller combined with a MOSFET in a single package.
The IRIS4013(K) is designed for use in AC/DC switching power supplies up to 230VAC nominal input, and is
capable of powers up to120W for a universal input. The device operates on a quasi-resonant or Pulse Ratio
Control (PRC) basis, 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
