Wholesale Switching Power Supply

Switching power supply [2] is the use of modern power electronics technology, control switch on and off time ratio, maintain a stable output voltage of a power supply, switching power supply generally consists of a pulse width modulation (PWM) control IC and MOSFET constituted. With the power electronics technology development and innovation, so that the switching power supply technology is constantly innovating. Currently, switching power supply with small, light weight and high efficiency characteristics are widely used in almost all electronic equipment, it is the rapid development of electronic information industry indispensable to a power mode.
