MC44604
High Safety Pulsed Mode
Standby GreenLine t
PWM Controller
The MC44604 is an enhanced high performance controller that is
specifically designed for off ? line and dc ? to ? dc converter applications.
Its high current totem pole output is ideally suited for driving a power
MOSFET.
The MC44604 is an evolution of the MC44603A. Like the
MC44603A, the MC44604 has been optimized to operate with

universal ac mains voltage from 80 V to 280 V. It also offers enhanced
safety and reliable power management thanks to its protection features
(foldback, overvoltage detection, soft ? start, accurate demagnetization
detection).
In addition, the MC44604 offers a new efficient way to reduce the
standby operating power by means of a so ? called pulsed mode
standby operation of the converter, significantly reducing the
converter consumption in standby mode.
