Overview
MC44604 High Safety Pulsed Mode Standby GreenLinet 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.
