Functional Description
The switching regulators are designed using the buck
converter topology. 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, to the load, and
Positive Switching Regulators
complished by varying the duty cycle (on to off 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 optimize customer ’s needs, additional options
and accessories are available.
