Offline Controllers | MC44608

The MC44608 is a high performance voltage mode controller designed for off-line converters. This high voltage circuit that integrates the start-upcurrent source and the oscillator capacitor, requires few external components while offering a high flexibility and reliability.

The device also features a very high efficiency stand-by management consisting of an effective Pulsed Mode operation. This technique enables the reduction of the stand-by power consumption to approximately 1W while delivering 300mW in a 150W SMPS.
