The MC44604 is an enhanced high performance controller that is
specifically designed for off–line and dc–to–dc 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, soft–start, 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).
In addition, the MC44604 offers a new efficient way to reduce the standby
operating power by means of a patented standby ladder mode operation of
the converter significantly reducing the converter consumption in standby
mode.
