Fixed Frequency, Variable Frequency,
Standby ModeThe MC44603 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 MC44603
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.
