L5991：Current Mode PWM
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.
