The MC44604 is an enhanced high performance controller that is specifically designed for offline and dctodc converter applications. The MC44604 is a modification of the MC44603. The MC44604 offers enhanced safety and reliable power management in its protection features (foldback, overvoltage detection, softstart, accurate demagnetization detection). Its high current totem pole output is also ideally suited for driving a power MOSFET but can also be used for driving a bipolar transistor in low power converters (< 150 W).
