Misconceptions in Internal Development of DC/DC Converters
Although most manufacturers have used purchased switching mode power supplies in their circuits, they are generally hesitant to use third-party DC/DC converters in their designs. There are two main reasons: on the one hand, DC/DC converters work with low DC power supply and belong to relatively simple components; on the other hand, they form part of the printed circuit board, so it is better to adopt a process to mount with other components. At first glance, developing converters seems to be a relatively simple task. But this is an illusion, because usually the surface looks simple devices, the details of the most prone to problems. In the design of DC/DC converters , some characteristics of analog technology often lead to very difficult problems. For example, printed lines produce capacitors or inductances that do not exist in circuit diagrams, which are usually unpredictable. In addition, the performance of transformer is not only affected by ferrite material, but also depen...
