Chargers & Adapters
Power Integrations offers a broad range of both highly integrated, high-voltage ICs and stand alone controllers for off-line power conversion in charger/adapter for cell phone, digital camera, cordless phone, networking and other applications. Our integrated IC solutions include a high voltage power switch combined with control and protection circuitry (and for InnoSwitch families a synchronous rectification driver) in a single device. This ensures high efficiency and reliability. Features include current limiting and thermal shutdown with automatic fault recovery capability to improve reliability and frequency jittering to reduce EMI.
PowiGaN is Power Integrations’ internally developed gallium nitride (GaN) technology. PowiGaN switches replace the traditional silicon transistors on the primary side, reducing switching losses and enabling power supplies that are more efficient, smaller and lighter than silicon alternatives. PowiGaN-based ICs achieve up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink.
