Description
The IRIS4011(K) is a dual mode voltage and current controller combined with a MOSFET in a single package.
The IRIS4011(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 60W 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.
