IRIS4009

Data Sheet No. PD60196 IRIS4009(K) INTEGRATED SWITCHER Features Primary current mode control, and secondary voltage mode control Vcc Over-voltage protection (latched) Over-current & over-temperature protection Quasi resonant, variable frequency operation 5 pin TO-220 and TO-262 8.0Ω Rds(on) max/ 650V MOSFET Fully Characterized Avalanche Energy IRIS4009 5 Lead TO-220 IRIS4009K 5 Lead TO-262 Packages 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.
