Application Description

With the promotion and landing of 5G communication in the country, higher requirements for 5G communication power supplies have also been generated. The entire power system of the 5G communication power supply must have high energy efficiency, high density and high reliability to provide the high level of power performance required.

In the switching power supply, the loss of the power semiconductor device accounts for about 30% to 80% of the total loss, so reducing the loss of the power semiconductor device is of great significance to improve the output power and efficiency. The loss of the power semiconductor device MOSFET commonly used in the switching power supply includes the switching loss, that is, the loss generated during the semiconductor opening and closing process, and the on-off loss, that is, the loss caused by the on-resistance or on-voltage drop during the steady-state opening of the semiconductor.

CoolSemi's SGT MOS and SJ MOS series products have been optimized for lower on-voltage drop and switching loss, as well as greater reliability.
