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.

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 package
• 0.97Ω Rds(on) max/ 650V MOSFET
• Fully Characterized Avalanche Energy
