High Performance Current Mode Controller - On Semiconductor

The MC44602 is an enhanced high performance fixed frequency current mode controller that is specifically designed for offline and high voltage dctodc 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. The MC44602 has several distinguishing features when compared to conventional current mode controllers. These features consist of a foldback Amplifier for overload detection, valid load and demag Comparators with a fault latch for short circuit detection, thermal shutdown, and separate high current source and sink outputs that are ideally suited for driving a high voltage bipolar Power Transistor such as the MJE18002 MJE18004 or MJE18006. Standard features include an Oscillator with a sync input, a temperature compensated reference, high gain error Amplifier and a current sensing Comparator Protective features consist of input and reference undervoltage lockouts each with hysteresis, cyclebycycle current limiting, a latch for single pulse metering, and a flipflop which blanks the output off every other Oscillator cycle, allowing output deadtimes to be programmed from 50% to 70%. This device is manufactured in a 16 pin dualinline heat tab package for improved thermal conduction . By ON Semiconductor
