A Rapid Design Method for Monolithic Switching Power Supply [Copy link]

Abstract: Monolithic switching power supply is a new type of switching power supply chip that became popular in the world in the 1990s. This article describes its rapid design method.

When designing a switching power supply, the first problem is how to choose a suitable monolithic switching power supply chip that can meet the requirements and not waste resources due to improper selection. However, this is not an easy task. One reason is that monolithic switching power supplies have now formed four major series and nearly 70 models. Even if different models of the same package are used, their output power is different; the second reason is that when selecting a chip, not only the designed output power PO must be known, but also the efficiency η of the switching power supply and the power loss PD of the chip must be determined in advance. The latter two characteristic parameters can only be measured when the switching power supply is designed and installed. They are unknown before design.
