MOTOROLA ANALOG IC DEVICE DATA
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.
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, cycle–by–cycle current limiting, a latch for
single pulse metering, and a flip–flop 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 dual–in–line heat tab package
for improved thermal conduction.
