Farnell adds InnoSwitch3 to its GaN-based portfolio

GaN-based products from Farnell now include Power Integrations’ InnoSwitch3 PowiGaN-based ICs. 

According to Power Integrations, PowiGaN technology reduces switching losses, enabling chargers, adapters and open frame power supplies to be more efficient, smaller and lighter than conventional silicon alternatives. PowiGaN-based ICs achieve up to 95 per cent efficiency across the full load range and up to 100W in enclosed adapter implementations without requiring a heatsink. 

Common applications for the ICs include auxiliary, standby and bias power supplies for appliances and white goods, computers and consumer products, utility meters, the smart grid and industrial power supplies.

The InnoSwitch3 product family features EcoSmart energy efficiency, ensuring devices can meet global energy efficiency regulations. Protection features include line over-voltage and under-voltage protection, output over-voltage and over-current limiting and over-temperature shutdown. 

The InnoSwitch3 products available from Farnell includes the InnoSwitch3-EP family, which is claimed to simplify the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. It combines primary and secondary controllers and safety-rated feedback into a single IC. Devices are available with standard and peak power delivery options, and commonly used auto-restart protection behaviours.

There is also the InnoSwitch3-Pro family, designed for the development of fully programmable, highly efficient power supplies in compact enclosures. The universal I²C interface aids dynamic control of output voltage and current, along with many configurable features. Telemetry provides reporting of programmed features and fault modes. InnoSwitch3-Pro ICs are suitable for AC/DC power supply applications where fine output voltage and current adjustment are necessary. 

The third member is the InnoSwitch3-CP family which incorporates a high voltage, primary side switch, primary and secondary controllers and safety-rated feedback in a single IC. The ICs offer a constant power profile and support the common combinations of latching and auto-restart behaviours required by applications such as quick charge and USB PD designs. The devices are available with and without cable-drop compensation.

InnoSwitch3 ICs are also available without PowiGaN technology, combining primary, secondary and feedback circuits in a single surface-mounted off-line flyback switcher IC. 

The portfolio of Power Integrations’ InnoSwitch3 products featuring PowiGaN technology is now available from Farnell in EMEA, element14 in APAC and Newark in North America.

Farnell is a business unit of Avnet.
