This article describes the design of a micro-transformer in monolithic technology for high frequencies comprising planar type coil and a magnetic circuit made of several layers of materials. This micro-transformer is integrated into a micro-converter of fly-back type. The Mohan method was used to determine the geometric parameters and the S-parameters were used to calculate technological parameters. The study of electromagnetic effects allowed us to show the role of ferrite, which is used to confine the magnetic field lines and minimize disruption of the neighbor ship. To validate the dimensioning of the geometrical and technological parameters, with the help of the software PSIM6.0, we simulated the equivalent electrical circuit of the converter containing the electrical circuit of the dimensioned planar micro-transformer
