Murata Power Solutions BAC1 Isolated 1W AC/DC Converters

Murata BAC1 isolated 1W AC/DC converters are compact and robust converters for use in connected and always-on devices, such as LED lighting, sensing, smart building, and metering applications.

The BAC1 is a compact total solution, providing a fully regulated 1W AC/DC converter in a board mount 6-pin SIP package, with a footprint measuring 33.53mm x 10.00mm. Keeping the total footprint small, the regulators require minimal external components to complete the design and have a total PCB area up to 75% smaller than competitive solutions.

Murata BAC1 converters operate from a universal 85VAC to 264VAC input or a 70VDC to 400VDC input, with output options of 5V, 12V, or 24V. They offer efficiency up to 74% and have an ultra-low 20mW standby power consumption to help meet demanding energy-saving requirements.

The converters have a tight line and load regulation to ensure a consistent output voltage, with 0.1% load regulation for all parts, 0.1% line regulation for 12V and 24V outputs, and 0.3% line regulation for 5V outputs.

The converters are designed for robust operation, with a -40°C to +85°C operating range in still air with no derating of the output. They provide 4kVAC isolation, reinforced insulation with a 264VAC working voltage, and short circuit protection. They’re also recognized with UL60950 and have many certifications.
