With the development trend of the electronic system based on diversiifed functions, and the more compact structure, it is necessary that the switch mode power supply achieve multi-channel output to meet the employment under the required volume. According to this analysis, our paper gives a introduction about the working principle and the design method of the non-isolated DC/DC converter includes multi-channel based on TPS40055PWP controller and LMZ14203 power modules both from TI, focusing on the technical dififculties and the corresponding solutions in the development process. Finally a demo board was designed based on the topology. Both simulation and test results showed that the circuit met design speciifcations.
