Description

technical field [0001] The invention relates to a switching power supply, in particular to a magnetically integrated switching power supply. Background technique [0002] In the traditional step-up switching power supply design, in order to ensure that the input current ripple is small, it is necessary to select a larger input filter inductance L. Increasing the inductance value also means increasing the size and weight of the power supply, and reducing the dynamic performance of the power supply. Not only that, but the traditional step-up switching power supply operating in continuous conduction mode has an irreversible right-half-plane zero point, which directly leads to low bandwidth and poor dynamic response of the power supply, so it cannot be well Meet the dynamic response requirements when the load changes. The structure of the traditional step-up switching power supply is as follows: figure 1 As shown, Vin is the input voltage, Vout is the output voltage, L is the...
