What is a power supply adapter? Power supply adapter, also known as external power sources, are generally used as power supply voltage conversion devices for small portable electronic devices and electronic devices. It is usually used in small electronic products such as mobile phones, LCD monitors and laptops etc. The function of the power supply adapter is to convert the high voltage of 220 volts at home into a stable low voltage of about 5 volts to 20 volts that these electronic products can work with so that they can work properly.

There are two main types of power supply adapters, switching power supplies and linear power supplies.

1. The switching power supply is a power supply that uses modern electronic technology to control the switching time ratio and maintain a stable output voltage. The switching power supply of the power supply adapter is generally composed of a pulse width modulation (PWM) control IC and a MOSFET.

2. The linear power supply converts AC through the transformer, rectifier circuit rectifier filter to obtain unstable DC voltage. In order to achieve high-precision DC voltage, the power supply adapter must regulate the output voltage through a voltage feedback circuit.
