The STEVAL-ISA071V2 demonstration board is a non-insulated SMPS capable of delivering a 4 W output over a wide input voltage range and is designed for a mains application requiring -5 V and +7 V, referred to neutral.

The basic concepts used in this design can also be applied for higher power outputs or different voltage ranges.

The SMPS generates outputs of 5 V and 12 V, referred to the output marked -5 V. The 5 V output is dedicated to supplying an MCU. This configuration allows the use of the MCU to directly drive a Triac (referred to neutral).

The 12 V output is used to supply additional circuits (relays, OA, etc.).
