Wurth Electronics has introduced a new generation of 1 W "fixed output voltage isolated SIP/SMT modules

     Wurth Electronics has introduced a new generation of 1 W "Fixed Output Voltage Isolation SIP/SMT module", adding a brand new product to the MagI³C FISM family of power modules. The series improves on the integrated voltage converter and features continuous short circuit protection (SCP) and higher isolation voltage. The nine new modules come in standard SIP-4, SIP-7 and SMT-8 packages that are compatible with the pins of previous MagI³C FISM products.

     The MagI³C FISM power module is a highly integrated DC/DC voltage converter with a fixed output voltage. The module contains power devices, transformers, input and output capacitors, which can work without external components and greatly reduce the workload of circuit design. This reduces development costs and allows new products to be brought to market faster. The entire product line is certified to the current UL62368-1 standard, but the new generation modules offer higher security. It will not be damaged by short circuit, and has high isolation voltage. The isolation voltage of SIP-4 module is up to 1.5kV, and the isolation voltage of SIP-7 and SMT-8 is up to 3kV, which can last for 60 seconds.

     This makes the new generation of MagI³C-FISM modules more suitable for functional isolation, avoiding ground loops and ground level shifts, as well as interference with signal paths or sensor systems. Such isolated voltage resistance is important when designing power supplies for interfaces and microcontrollers in test equipment or industrial electronics.

     Wurth Electronics measured the power supply module with the filter and listed the test results in the specification. We found that the radiation and conducted emission of the MagI³C-FISM module was below the test limits of EMC standard EN55032 / CISPR32 Class B. The new MagI³C-FISM line is available off the shelf. Including easy to assemble through-hole in-line SIP-4 and SIP-7 packages, as well as hand soldered SMT-8 packages, ideal for prototyping,
