element14 Expands Power Integrations Product Portfolio with InnoSwitch™ 3 Series ICs

InnoSwitch3 family of ICs uses PowiGaN™ technology to deliver up to 95% efficiency across all load conditions and up to 100W output power without heat sink in enclosed adapter applications

Shanghai, China, November 26, 2021 – Farnell Farnell, a global distributor of electronic components and solutions under Avnet, announced the supply of the InnoSwitch3 series ICs using PowiGaN technology, further expanding its Power Integrations product lineup. By introducing the InnoSwitch3 series of products, Farnell Farnell can provide design engineers with a richer selection of gallium nitride (GaN) devices, thereby supporting them in developing new products with higher energy efficiency.

Compared to traditional silicon transistors, Power Integrations' PowiGaN technology further reduces switching losses, enabling more efficient, compact and lightweight chargers, adapters and open-frame power supplies. IC devices using PowiGaN technology can achieve efficiencies of up to 95% under various load conditions and can achieve output powers of up to 100W without heat sinks in enclosed adapter applications. Common applications include:

• Auxiliary, backup and bias power supplies for home appliances and white goods

• Computers and consumer electronics

• Water, electricity and gas meters

• Smart Grid

• Industrial Power Supply

InnoSwitch3 series ICs also use EcoSmart™ energy-saving technology, which enables devices to easily meet various global energy efficiency standards. This series of products integrates multiple protection functions, including line overvoltage and undervoltage protection, output overvoltage and overcurrent limiting, and over-temperature shutdown. At present, the InnoSwitch3 series products available from element14 include:

• The InnoSwitch3-EP family of ICs greatly simplifies the design and manufacture of flyback power converters, especially those in compact enclosures or where high efficiency is required. The devices integrate the primary and secondary controllers and safety standard feedback mechanisms into a single IC and offer standard and peak power output options, as well as the popular auto-restart protection feature.

• The InnoSwitch3-Pro family of ICs can be used to develop fully programmable, high-efficiency power supplies in compact housings. Its universal I²C interface enables dynamic control of output voltage and current and provides a variety of configurable features. It also incorporates telemetry technology to provide monitoring reports of set functions and fault modes. InnoSwitch3-Pro ICs are suitable for AC-DC power supply applications where output voltage and current need to be precisely regulated.

• The InnoSwitch3-CP family of ICs integrates a high voltage primary-side switch, primary and secondary controllers, and safety standard feedback mechanisms into a single IC, featuring constant power configuration and a combination of common features such as latch-off and auto-restart required for applications such as fast charging and USB PD designs. The devices are available with and without cable drop compensators.

In addition to the EP, Pro and CP series, the InnoSwitch3 family also offers IC devices without PowiGaN technology. All InnoSwitch3 ICs integrate the primary, secondary and feedback circuits into a single surface mount offline flyback switcher IC.

Lee Turner, Director of Semiconductors and SBCs at Farnell and element14, said: “We are delighted to be expanding our Power Integrations portfolio with the introduction of the InnoSwitch3 family of products using PowiGaN technology. Power Integrations’ highly integrated chips can eliminate millions of electronic components in AC-DC power supplies, gate drivers and LED lamps, while increasing the efficiency of end products. With the InnoSwitch3 family of ICs, our customers will be able to develop new products for applications ranging from milliwatts to megawatts, with efficient transmission and low energy consumption.”

Power Integrations is a leading innovator in high-voltage power conversion semiconductor technology. Its integrated circuits enable compact, energy-efficient AC-DC power supplies for a wide range of electronic products in smartphones, home appliances, smart home and commercial automation, smart meters, LED lighting, and industrial and IoT applications. The company also offers PI Expert™ Online automated power design software that supports silicon MOSFETs and PowiGaN devices. This web application helps users select the most appropriate components and generates a complete schematic, magnetic device design, and bill of materials (BOM) based on the basic parameters entered, thereby speeding up the design process.

Design engineers can now purchase a more comprehensive semiconductor product portfolio through element14. Customers can also access online resources, data sheets, application notes, videos and webinars on the element14 website free of charge, and can get technical support 8 hours a day, 5 days a week.

Power Integrations’ InnoSwitch3 family of products featuring PowiGaN technology is available now from Farnell (EMEA), element14 (APAC) and Newark (North America).
