MARKING  
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.
