The MC44603A is an enhanced high performance controller that is
specifically designed for off–line and dc–to–dc converter applications. This
device has the unique ability of automatically changing operating modes if
the converter output is overloaded, unloaded, or shorted, offering the
designer additional protection for increased system reliability. The
MC44603A has several distinguishing features when compared to
conventional SMPS controllers. These features consist of a foldback facility
for overload protection, a standby mode when the converter output is slightly
loaded, a demagnetization detection for reduced switching stresses on
transistor and diodes, and a high current totem pole output ideally suited for
driving a power MOSFET. It can also be used for driving a bipolar transistor
in low power converters (< 150 W). It is optimized to operate in
discontinuous mode but can also operate in continuous mode. Its advanced
design allows use in current mode or voltage mode control applications.
