Abstract

Switch Mode Power Supply (SMPS) is a common product used in the electronic industries. This project is about the switching mode power supply using discontinuous . mode buck-boost converter .topology. Basically, SMPS design is a very interesting to learn, where the switching and duty cycle can determine the output of it result. SMPS is also a common item that can be found in the electronic market. Mostly all the electronic g~dget is accompany with an SMPS. This is where show that the SMPS have gap ·differences with 'the linear power supply. For example: Laptop, hand phone charger, computer and many more. As the electronic industries grower larger in Malaysia, it is a suitable the project to be done during the PSM 1. In the future may be the SMPS size and efficiencies will incredibly increase. In this project we need to design a buck -boost converter that able to make the result of step up and step down voltage of 12V to 5V and 24V. From here we need to determine each of the components that will effect the whole circuit duty cycle, and to make sure the circuit always in discontinuous mode.
