Data SheetNo. PD60190-CIRIS4015(K)INTEGRATED SWITCHERFeatures • Packages 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 package • 0.97Ω Rds(on) max/ 650V MOSFET • Fully Characterized Avalanche Energy IRIS4015 IRIS4015K 5 Lead TO-220 5 Lead TO-262 Descriptions The IRIS4015(K) is a dual mode voltage and current controller combined with a MOSFET in a single package. The IRIS4015(K) is designed for use in AC/DC switching power supplies up to 230VAC nominal input, and is capable of 180W for a universal line input. The device operates on a quasi-resonant or Pulse Ratio Control (PRC) basis, and thereby variable frequency operation.
