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 1769405x41 series FISM family achieves typically an efficiency of 84% up to 87%. The series is available in a SMT-8 package (13.20 x 11.4 x 7.55mm).
