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.
