A direct current (DC) power supply is a device that converts alternating current (AC) to direct current (DC), or from one voltage to another. Most electronic devices and circuits are powered by a DC power supply.
DC power supplies are used in a wide variety of electronic devices and circuits. They can be used to power anything from small portable devices to large industrial machines. DC power supplies are also found in many types of scientific and medical equipment. Some common examples of devices that use DC power supplies include:
Computers and computer peripherals
Televisions and video players
Cell phones and other portable electronic devices
most mobile repair technicians used DC power supply to switch ON a smart-phone without their batteries. the Supply can be used to substitute for the Cell Phone GND, +VBAT Battery Voltage when doing hot testing on the Mobile PCB.
