  • 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.).

    Key Features

    • Input:
      • VIN: 85 - 264 Vrms
      • f: 45 - 66 Hz
    • Output:
      • 12 VDC± 10% (referred to -5 V), 160 mA
      • -5 VDC ± 4%, 400 mA
    • Maximum output power: 4 W (range is up to 6 W for EU)
    • Standby power: 35 mW at 230 VAC
    • Short-circuit protected
    • Insulation: non-insulated; N connected to output GND
    • EMI: in accordance with EN55022 class B
    • RoHS compliant
