External Components Reliable

and Flexible SMPS Controller

IL44608

DESCRIPTION

The IL44608N is a high performance voltage mode controller

designed for off–line converters. This high voltage circuit that inte-

grates the start–up current source and the oscillator capacitor, re-

quires few external components while offering a high flexibility and

reliability.

The device also features a very high efficiency stand–by man-

agement consisting of an effective Pulsed Mode operation. This

technique enables the reduction of the stand–by power consumption

to approximately 1.0 W while delivering 300 mW in a 150 W

SMPS.
