The difference between switching voltage regulators and switching power supplies

1, switching power supply is a larger concept than the price, it can include inverters (low-voltage to high-voltage, UPS precursors), low-voltage to high-voltage (daily commonly used small chargers, etc.).

2, switching regulator, the key word is in the voltage regulation, so the output of the switching power supply has a negative feedback sampling circuit, can play a role in voltage regulation, usually the efficiency of the switching power supply will be relatively high, the input dynamic range is relatively large, the dynamic response is better, so it is now widely used.
