MC44604 Datasheet (ON Semiconductor)

MC44604, PWM Controller

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
