IRIS4011K

Data SheetNo. PD60188-B IRIS4011(K) INTEGRATED SWITCHER Features • Primary current mode control, and secondary Packages 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 • 3.9Ω Rds(on) max/ 650V MOSFET • Fully Characterized Avalanche Energy IRIS4011 5 Lead TO-220 IRIS4011K 5 Lead TO-262 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.
