What is a linear adapter and a switching power adapter
. Linear power supply efficiency is low, and switching power supply efficiency is higher. But the linear power supply EMI is low, and the switching power supply EMI is higher, especially the low power. So the use of different!
Linear adapters and switching power supplies are commonly referred to as linear power supplies and switching power supplies. Linear power supply refers to the power of the regulator tube work in a linear state, while the switching power supply regulator tube to work in the switch state.
Ordinary through the frequency transformer re-finishing filter series adjustment regulator (such as integrated chip 78XX) is a linear adapter; use of switching power supply called switching power adapter.
