There are many types of DC buck schemes, common ones include linear regulators, switching regulators and buck converters.
Linear regulators reduce voltage by adjusting resistance and are suitable for low power applications. The switching regulator adjusts the voltage through the switching action of the switching tube, which has high efficiency and is suitable for high-power applications. Step-down converters achieve voltage reduction through transformers and electronic switches, and are suitable for a wide range of voltage transformations. When using, select the appropriate pressure reduction scheme according to the specific requirements, and perform the operation according to the use method provided by the scheme.
