IR4007K

ADVANCE INFORMATION Data SheetNo. PD60183 IR4007K Switched Mode Power Supply IC 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 • 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 voltage mode control Typical Connection Diagram Vin (AC/ DC) Vout (DC) 3 Drain Vcc 4 IR4007K FB Source Gnd 5 1 2 *Please note that this datasheet contains advance information which could change before the product is released to production. www.irf.com 1 IR4007 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.
