Myrra’s 47000 Series Switch-mode AC/DC Modules are attracting a lot of interest!

Switch-mode power supplies (AC/DC converters) are now replacing standard linear power supplies in many applications. Whereas the linear circuit uses an often bulky steel laminated transformer, the MYRRA 47 series switch mode modules offer 5W capability in the “pin for pin” footprint of the linear EI30 transformer. Add to this the excellent efficiency, increased power to space ratio, energy saving through low standby losses, significant weight reduction, saving in PCB landscape and lower component count, not to mention the universal input voltage possibility, the attractions become clear!

Myrra’s 47000 series switch mode power-supply modules, based on Flyback topology, are a cost-effective and time saving alternative to linear power supplies using 50/60Hz transformers.

In any AC/DC application up to a 5W power rating, they replace the 50Hz transformer, fuse, bridge rectifier, filtering capacitor, and voltage regulator all within a single package.

Utilizing the same footprint as an E130 transformer this will save space and be ready for direct soldering into a PCB, meaning you could upgrade your application without redesign of the PCB.

The very low standby power consumption meets the requirements of Energy star/EC Code of Conduct
