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.
