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. The integrated IC includes high voltage power switch combined with control , protection circuitry and for InnoSwitch families also synchronous rectification driver on single chip. While the BJT control IC, uses the most advance BJT drive system, emitter switch/base driver, to ensure high efficiency and high 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.
