Not for new design

These versatile SMPS control ICs comprise digital and

analog functions which are required to design high-

quality flyback, single-ended and push-pull converters

in normal, half-bridge and full-bridge configurations.

The component can also be used in single-ended

voltage multipliers and speed-controlled motors.

Malfunctions in electrical operation are recognized by

the integrated operational amplifiers, which activate

protective functions.
