Power supply IC for low power AC adapters

摘要

This paper has introduced an overview of the FA5702P power IC for switch-mode power supply control, developed for the application to 5 W-class low-power AC adapters. This IC contains an internal power MOSFET and has the advantage of low current consumption. Therefore, it helps to reduce the standby power consumption of AC adapters and the number of their circuit components. Fuji Electric will respond further to market needs by expanding the product line of power ICs for switch-mode power supply control to provide devices suitable for application to a variety of applications and output requirements.
