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.
Power Integrations offerings include integrated, high-voltage ICs for off-line power conversion in Notebook Adapter power supply applications. Notebook Adapter applications utilize the TOPSwitch-JX family devices, which enable highly efficient and compact laptop power supplies to be in a sealed enclosure, to withstand high ambient temperatures (e.g., 40 °C), and provide no-load performance <90 mW at 230 VAC.
TOPSwitch-JX is also available in a ultra-low-profile package (eDIP Package), that enables remarkably slim, compact, and lightweight power supplies from 20 to 100 watts.
Each IC includes a high-voltage switch with a feature-rich PWM controller in one device. 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.
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.
