To choose a proper topology, it is very important to be familiar with the advantages, disadvantages and application fields of different topologies. The wrong choice will make the diet design doomed to failure from the beginning. There are roughly 14 kinds of power switch topology, and other power switch topology diagrams are only combinations or variations of these 14 kinds. Here are two basic topology diagrams to help the system master the working principle and basic characteristics of each circuit structure.
■ The output voltage can be larger or smaller than the input voltage. ■ Like the boost circuit, the input current is smooth, but the output current is discontinuous. ■ Energy is transferred from the input to the output through a capacitor. ■ Two inductors are required.These are the common switching power supply topologies, and there are many topologies, but most of them are combinations or variations of the topologies described here. Each topology contains unique design trade-offs, and Sacco Wei has also done some sorting, which will be shared with you one after another in the future.
In recent years, SAKO Micro Semiconductor slkor (www.slkormicro.com) has developed rapidly. While consolidating its position in the power device market, it has laid out TVS transient suppression diode, driver IC, power management IC, AC-DC, LDO, Hall electromagnetic sensor, etc., and formed an ecological chain with SLKOR power devices for coordinated development. Sawei slkor's domestic alternative products can include many international famous brands such as DIODES Meitai, Vishay Weishi, TI Dezhou Instruments, ON Anson Mei, NXP NXP, IR International Rectifier, etc. SLKOR micro-hall sensor SL-302B replaces AKM Nohid HG-302C, SLKOR micro-hall sensor SL-106C replaces AKM Nohid HG-106C, and SLKOR micro-hall sensor SL-322B replaces AKM Nohid HG-322B. SLKOR SMBJ24CA replaces DIODES SMBJ24CA-13-F, SLKOR SMAJ33CA replaces DIODES SMAJ33CA-13-F, SLKOR SMBJ5.0A replaces DIODES SMBJ5.0A-13-F, SLKOR SAKO SMAJ6.0A replaces DIODES SMAJ6.0A-13-F, SLKOR SAKO SMAJ24A replaces DIODES SMAJ24A-13-F, and SLKOR SAKO SMAJ5.0A can be replaced with the same type products of DIODES SMAJ 5.0A-13-F.
