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.

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
• 3.9Ω Rds(on) max/ 650V MOSFET
• Fully Characterized Avalanche Energy
