The MC44605 is a high performance current mode controller that is specifically designed for offline converters. The MC44605 has several distinguishing features that make it particularly suitable for multisynchronized monitor applications. The MC44605 synchronization arrangement enables operation from 16 kHz up to 130 kHz. This product was optimized to operate with universal ac mains voltage from 80 V to 280 V, and its high current totem pole output makes it ideally suited for driving a power MOSFET. The MC44605 protections provide well controlled, safe power management. Safety enhancements detect four different fault conditions and provide protection through a disabling latch.
