IRIS4009

5 Lead TO-220

IRIS4009K

5 Lead TO-262

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.
