The KA3504 is complete output supervisory circuitry intended for use in the secondary side of the switched mode power supply. It provides all the functions necessary to monitor and control the output of the power supply system. Power good signal generator, Remote on and off control, some precision protection features against over-voltage and over-current are implemented. It directly senses all the output rails for OVP without any external dividers. As for output control, power good output (PGO) and Fault Protection output (FPO) are also included. Utilizing a minimum number of external components, the KA3504 offers a simple and cost effective solution, greatly reducing PCB board space for power supply system.
