NEW: Building Your Own Power Supply With PI

Power Integrations offers a broad range of highly integrated, high-voltage ICs for industrial applications. Each IC includes a ≥700 V power MOSFET combined with control and protection circuitry on a single chip. Features include current limiting and thermal shutdown with automatic fault recovery capability to improve reliability, frequency jittering to reduce EMI and EcoSmart™ technology to dramatically reduce standby energy waste.
