What are the differences between linear regulated power supplies and switching power supplies?
Switching power supply efficiency is high, and can be boost can also buck. Linear power supply can only buck, and low efficiency. Switching power supply will produce high-frequency interference, linear power supply is no interference. Each with advantages and disadvantages.
Linear regulated power supply is directly connected in series with a controllable adjustment element to divide the input DC voltage to achieve voltage conversion and regulation, essentially equivalent to a variable resistor in series.
Switching power supply is through the DC into a high-frequency pulse, and then the electromagnetic conversion to achieve voltage conversion and regulation.
