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.

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.
