Functional Description and Application
The general-purpose single-ended switch-mode power supply device for the direct
control of SIPMOS power transistors incorporates both digital and analog functions.
These are required for the construction of high-quality flyback, forward and choke
converters. The device can be likewise used for transformer-less voltage multipliers and
variable-speed motors.
Faults occurring during operation of the switch-mode power supply are detected by
comparators integrated in the device which initiate protective functions.
In addition, pairs of power supplies can be synchronized in antiphase. In-phase or
antiphase synchronization is possible when more than two power supplies are involved.
