Description
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.
