General 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.

Key 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.
