Description
This demonstration board is a multi-output SMPS
which can be used to supply an alarm system.
The circuit is composed of an AC-DC single
output converter with an approximate power
capability of 60 W, while the other outputs are
obtained by means of DC-DC converters. The
power supply also integrates a battery charger
circuit in order to charge a standard SLA 12 V
battery.
