Next gen isolated power modules deliver continuous short-circuit protection

WüRTH ELEKTRONIK MagIC FISM power modules next generation 1W ‘Fixed Isolated SIP/SMT voltage converter modules provide continuous short-circuit protection (SCP) and increased isolation voltage. The nine new modules in standard SIP-4, SIP-7 and SMT-8 packages are pin-to-pin compatible with the previous MagIC FISM. Modules are fully integrated dc-dc voltage converters with a fixed output voltage. Products contain the power stage, transformer, input and output capacitance. No external components are required for operation, and circuit design effort is minimal. This reduces development costs and makes it possible to go to market quickly with new applications. The entire product line is certified to the current UL standard UL62368-1, but the new modules offer even more safety. They cannot be destroyed by short circuits and can withstand their isolation voltage of 1.5 kV for the SIP-4 modules and 3 kV for SIP-7 and SMT-8 for a full 60 seconds.
