5P30018NBGI is a designed power module product which is often used in power supply systems. It has two parts, structural design and electrical design. Structurally, it is composed of two parallel MOSFETs, a chip capacitor, a center tapped inductor and a diode. Its electrical assembly design and working principle indicate that it can provide up to 8A of average current, peak current up to 18A, low on-state resistance and low power dissipation. In addition, it also provides scalable variable voltage control.

The application field of 5P30018NBGI is mainly to provide power supply and control the operating current of power devices. Such as lighting, industrial control, power digital products, computer peripheral devices, communication, etc. it can also serve as backup power for system battery and voltage output circuit for power tools.

Working principle of 5P30018NBGI power module is based on the connection of two MOSFETs. Each MOSFET is connected to the center tap of the inductor. The basic principle is to control the pulse width of the MOSFETs to control the output current of the inductor. When the power module is turned on, the chip capacitor provides the voltage for the power module. Once the gate pulses start coming through, the voltage of the chip cap is decreased. The voltage decrease regulates the on and off of the MOSFETS, so does the inductor. The output current is proportional to the input voltage. The output voltage of 5P30018NBGI is regulated by the Vfb pin on the Rectifier module.

To sum up, 5P30018NBGI power module is widely used in power system and industrial control fields. It has the advantages of low on-state resistance, peak current up to 18A, scalable variable voltage control, and low power dissipation. The key principles of working include controlling the pulse width of the MOSFETs and regulating the voltage decrease.
