MC44602P2 Datasheet PDF - ON Semiconductor

●High Performance Current Mode Controller

●The MC44602 is an enhanced high performance fixed frequency current mode controller that is specifically designed for off–line and high voltage dc–to–dc converter applications. This device has the unique ability of changing operating modes if the converter output is overloaded or shorted, offering the designer additional protection for increased system reliability.

●•Separate High Current Source and Sink Outputs Ideally Suited for Driving Bipolar Power Transistors: 1.0 A Source, 1.5 A Sink

●•Unique Overload and Short Circuit Protection

●•Thermal Protection

●•Oscillator with Sync Input

●•Current Mode Operation to 500 kHz Output Switching Frequency

●•Output Deadtime Adjustable from 50% to 70%

●•Automatic Feed Forward Compensation

●•Latching PWM for Cycle–By–Cycle Current Limiting

●•Input and Reference Undervoltage Lockouts with Hysteresis

●•Low Startup and Operating Current
