Switch Mode Power supply, switching Mode Power supply, switching converter. Is a high-frequency electrical energy conversion device, is a kind of power supply unit. Its function is to convert a bit of voltage through different forms of architecture into the voltage or current required by the user. The input of switching power supply is mostly AC or DC power supply, while the output is mostly DC power supply equipment, such as personal computer, switching power supply is to carry out the voltage and current conversion between the two. Switch power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment and other fields. Switching power supply is different from linear power supply. The switching transistors used in switching power supply are mostly switched between full-open mode and full-closed mode. Both of these models have the characteristics of low dissipation. Switching between switches has a high dissipation, but a short time, so it saves energy. The switching power supply consists of main circuit, control circuit, detection circuit and auxiliary circuit. The power electronic devices used in switching power supply are mainly diode, IGBT, MOSFET and transformer.

We offer a variety of models and specifications:

      Taking 4N65 as an example, it has the electrical parameters of 4A and 650V, the reverse recovery time TRR is 430nS, and the on resistance RDS (on) is 2.1 ohm@vgs = 10v.
