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 1779405x11 series of the FISM family achieves typically an efficiency of 83% up to 88%. The series is available in a SIP-4 package (11.60 x 7.55 x 10.16mm).
