IR4007K
Switched Mode Power Supply IC
Descriptions
Features
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.
• 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

ADVANCE INFORMATION
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are
absolute voltages referenced to terminals stated, all currents are defined positive into any lead. The thermal resistance and
power dissipation ratings are measured under board mounted and still air conditions.
