Brief description: Linear power supply is a traditional power supply solution that achieves stable DC output through linear regulation. The core working principle of a linear power supply can be divided into two steps: first, using a power frequency transformer to reduce 220V AC power to the required voltage value,

Brief description: Switching power supply is a power supply solution that utilizes high-frequency switching technology to achieve efficient energy conversion. Unlike traditional linear power supplies, it does not allow the regulator to operate in the linear region, but instead allows the power switch to alternate between saturated conduction (with almost
