The STEVAL-ISA071V1 switched-mode power 
supply (SMPS) demonstration board is dedicated 
to mains applications requiring -5 V and +7 V 
referred to neutral. The non-isolated SMPS is 
capable of delivering 4 W of output power over a 
wide input voltage range. This capability can also 
be applied to higher power outputs or different 
voltage ranges.

The SMPS generates 5 V and 12 V. The 5 V can 
be used to supply the MCU, directly driving a Triac 
connected to neutral, and the 12 V can be used to 
supply additional circuits, such as relays, OAs, 
etc.
