ROHM OPM DC-DC

ROHM DC/DC converters feature high efficiency, few external components, built-in output switches, multiple functions, and easy placement.

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)

Typical Applications (Basic)

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
