UN 0031a-P V.1 HEIR319404R0001 power signal converter module

UN 0031a-P V.1 HEIR319404R0001 Power converter is mainly used to convert a form of socket into another form or more than one form of socket, as well as mobile phone charging, electric vehicles are also a class of power converter. It is mainly used to supply power to another kind of electric appliance. UN 0031a-P V.1 HEIR319404R0001 The principle of DC-DC power converter is to use inductors and capacitors as energy storage components to complete the voltage conversion function, the main role is to efficiently achieve voltage conversion and stable output. Another difference between a DC-DC power supply and an LDO power supply is that a DC-DC power supply can either step-down, step-up, or reverse phase (positive voltage to negative voltage), while an LDO power supply can only step-down. It works by comparing the output voltage to the reference voltage through a divider resistor to form a feedback. When the output voltage decreases and falls below the reference voltage, the comparator output reverses and triggers the oscillating circuit to begin operation. The oscillating circuit outputs a pulse of fixed time, which is used to control the conduction of the MOS tube. Otherwise the MOS tube will be cut off. The on-off is controlled by an oscillator, and the cut-off time depends on the load. In this way, the output voltage can be controlled.
