Descriptions

The IR4007 is a dual mode voltage and current controller combined with a MOSFET in a single Package.

The IR4007 is designed for use in AC/DC and DC/DC switching power supplies upto 100VDC nominal 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 TO262 package

• 0.4Ω Rds(on) max/ 200V MOSFET

• Fully Characterized Avalanche Energy
