DC-DC refers to a switching power supply, refers to the DC-DC conversion.

Jan 05, 2018

DC switching power supply is the core DC / DC converter. Therefore, the classification of DC switching power supply is dependent on DC / DC converter classification. In other words, DC switching power supply classification and DC / DC converter is basically the same classification, DC / DC converter is basically the classification of DC switching power supply.


The switching power supply is a kind of power supply that uses modern power electronics technology to control the turn-on and turn-off time ratio of the switch tube and maintain a stable output voltage. The switching power supply generally consists of a pulse width modulation (PWM) control IC and a MOSFET. With the development of power electronics and innovation, making the switching power supply technology is constantly innovating. Currently, the switching power supply is widely used in small, lightweight and high efficiency almost all of the electronic equipment, is the rapid development of today's electronic information industry, a power supply.
