Description
MC44608
Few External Components Reliable and Flexible SMPS Controller
The MC44608 is a high performance voltage mode controller designed for off--line converters. This high voltage circuit that integrates the startup current source and the oscillator capacitor, requires few external components while offering a high flexibility and reliability.
The device also features a very high efficiency standby management consisting of an effective Pulsed Mode operation. This technique enables the reduction of the standby power consumption to approximately 1.0 W while delivering 300 mW in a 150 W SMPS.
