The Wurth Elektronik FISM power module family is an unregulated, functional isolated, fully integrated DC/DC converter. The module integrates the switching power stage, control circuitry, transformer and input/output capacitors. The module requires no external components for operation thus reducing design effort and complexity to a minimum. The FISM ensures fast time to market and low development costs. The 1779405x41 series of the FISM family achieves typically an efficiency of 80% up to 85%. The series is available in a SIP-7 package (19.65 x 7.05 x 10.16mm).
