ST STEVAL-ISA033V1 55 W flyback SMPS demonstration board for alarm system based on the L5991 STP12NK80Z handbook
The STEVAL-ISA033V1 is a demonstration board designed as a multi-output Switched Mode Power Supply (SMPS) for alarm systems. It utilizes an AC-DC single output converter with an approximate power capability of 60 W, while additional outputs are generated via DC-DC converters. The board also integrates a battery charger circuit capable of charging a standard SLA 12 V battery.
