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 in the form of flux. During the off period, this energy
forces the current to continue flowing through the output, to
the load and back through the freewheeling diode. Regula-
tion is accomplished by varying the on to 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 trans-
former with rectifier). To optimise customer’s needs, addi-
tional options and accessories are available.
