    Product Series

    Three-terminal Step-down DC/DC Converters

    Step-down DC/DC Converters (Non-isolated)

    Negative DC/DC Converters (Non-isolated)

    Isolated DC/DC Converter


    Feature

    ・  High efficiency

    High energy conversion factor (85 to 93%) contributes to compact, power-saving supplies.

    ・  Few external parts

    Because the external part is only two condensers, it can compose a powersupply circuit easily.

    ・  Internal output switch

    Enables full use of power saving feature.

    ・  Wider input voltage range

    Can operate with unregulated mains. (BP5220A/5221A: 8 to 38V)

    ・  Universal

    Wide applicability (i.e. output switches, protection circuits)

    ・  Small footprint

    SIP package requires less mounting space. (Board footprint: 65mm2)

    ROHM OPM AC-DC

    ROHM AC/DC converter with a wide voltage range is the best choice for industrial equipment, lighting equipment and home appliances.


    Product Series

    Non-isolated AC/DC Converter

    Isolated AC/DC Converter


    Feature

    ・ No transformer (Non-isolation)

    Few external components required, simplifying the DC power supply.

    ・ Reduces the size and weight of the power supply unit (Non-isolation type)

    Footprint and weight reduced to 1/4th and 1/30th the value, respectively, compared to transformer-equipped power supplies.

    ・ Wider input voltage range
