IRIS4007

Data Sheet No. PD60183-C IRIS4007(K) INTEGRATED SWITCHER Features • Primary current mode control, and secondary voltage mode control • Vcc over-voltage protection (latched) • Over-current and over-temperature protection • Quasi resonant, variable frequency operation • 5 pin TO-220 and TO-262 package • 0.4Ω Rds(on) max/ 200V MOSFET • Fully Characterized Avalanche Energy Packages IRIS4007 5 Lead TO-220 IRIS4007K 5 Lead TO-262 Descriptions The IRIS4007(K) is a dual mode voltage and current controller combined with a MOSFET in a single Package. The IRIS4007(K) are designed for use in AC/DC and DC/DC switching power supplies upto 100VDC nominal input and is capable of 30W for a nominal 48V input. The device can operate in either a quasi-resonant or Pulse Ratio Control (PRC) mode, and thereby variable frequency operation.

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.
