Functional Description
The switching regulators are using the buck topology. The
input is not electrically isolated from the output. During the on
period of the switching FET, 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 and the freewheeling diode to the
load. Regulation is accomplished by varying on/off duty cycle.
allocation, identification of LED, test sockets, and optional
potentiometer.
Label with input voltage range, output voltage and current,
protection degree, batch and serial no., and data code
including production site, version, and date of production.
Switching frequency is approx. 100 kHz. The converters exhibit
an undervoltage monitor to prevent high currents at low input
voltage, but no overvoltage monitor.
These regulators are ideal for applications, where an input to
output isolation is not necessary or where it is already provided
by an external front end, e.g. a transformer with rectifier. To
optimize customer ’s needs, various options and accessories
are available.
