VNB28N0413TR

The VNB28N0413TR is a power switching IC for various applications in the Power Management Integrated Circuit (PMIC) industry. It is specifically designed for automotive and other applications that require high levels of EMI performance. This power switching IC is made up of two separate power switches, the semiconductor half-bridge and the LCFB-Diode flyback. The combination of these two different power switches provides an integrated solution to achieve more efficient power distribution with increased flexibility.

The semiconductor half-bridge consists of two power transistors, a p-channel and an n-channel. These transistors provide a low on-resistance, as well as a low gate-drain capacitance, allowing for higher switching frequencies. The LCFB-Diode flyback provides a freewheeling inductor that keeps the output voltage regulated and allows for a more efficient power conversion. Both products are available in small, surface-mount packages.

The VNB28N0413TR is ideally suited for use in automotive power systems such as DC/DC converters, battery chargers, telecommunications, industrial, and medical applications. It is capable of handling large loads with a wide range of operating temperatures and voltages, as well as providing efficient power transfer. Additionally, the combination of the two power switches limits the amount of EMI generated, which is essential for these applications.

The working principle of the VNB28N0413TR power switching IC is simple. When the power switch is turned on, current flows through the p-channel and n-channel transistors. This current then activates the LCFB-Diode flyback, which provides the regulation needed to keep the output voltage constant. The LCFB-Diode flyback also ensures that any excess power is dissipated as heat, thus reducing the risk of overloading the system. Furthermore, the combination of the two power switches allows for the switching of both positive and negative voltages, enabling the device to be used in a variety of applications.

The VNB28N0413TR power switching IC is a powerful and efficient addition to the PMIC industry. It provides efficient power distribution and a low EMI profile, making it well suited for automotive, telecommunications, industrial, and medical applications. The two power switches also provide a cost-efficient solution, as well as ensure efficient power transfer without the need for separate components.
