Description
The IRIS4009(K) is a dual mode voltage and current controller combined with a MOSFET in a single package.
The IRIS4009(K) is designed for use in universal and single input AC/DC and DC/DC switching power supplies
and is capable of powers up to 30W for a universal line 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.
