Enabling Predictable Success Power Integrations helps designers reduce the complexity of their power supply design and achieve more predictable success. Our highly integrated ICs eliminate components from power supply designs reducing board, layout and assembly costs and improving reliability. We combine a high-voltage MOSFET switch with a controller on a single chip to provide key power supply functions, such as: High-voltage start-up Short-circuit and open-loop protection Programmable current limit Line undervoltage and overvoltage protection Output overvoltage protection Accurate overtemperature and overpower protection Soft-start Feedback compensation Remote on/off
