In this paper, a design technique of SMPS using plannar transformer is described. The application of plannar transformer can solve the space problem which occurs when it is installed on PCB since plannar transformer has low profile. In addition a lossless snubber circuit IS added to reduce the device stress and to Improve the system efficiency The designed system is verifed by simulation and experiment with comparison of efficiency between the system using conventional tran-sformer and the system using plannar transformer.
