Functional Description
The switching regulators are designed using the buck con-
verter topology. See also:
Technical Information: Topolo-
gies. The input is not electrically isolated from the output.
During the on period of the switching transistor, current is
transferred to the output and energy is stored in the output
choke. During the off period, this energy forces the current
to continue flowing through the output choke to the load
and back through the freewheeling diode. Regulation is
accomplished by varying the on/off duty ratio of the power
switch.
These
regulators
are
ideal
for
a
wide
range
of
applications, where input to output isolation is not
necessary, or where already provided by an external front
end (e.g. a transformer with rectifier). To optimise
customer’s needs, additional options and accessories are
available.
