Power Integrations delivers millionth GaN-based InnoSwitch3 IC

Power Integrations of San Jose, CA, USA, which provides high-voltage integrated circuits for energy-efficient power conversion, has delivered its one-millionth InnoSwitch3 switcher IC featuring its PowiGaN gallium nitride technology.

CEO Balu Balakrishnan presented the millionth GaN-based IC to Steven Yang, CEO of Anker Innovations in an event at the latter’s Shenzhen headquarters. Anker is a manufacturer of chargers and adapters, supplying retailers worldwide with powerful, compact USB PD adapters and a range of chargers and adapters for laptops, smart mobile devices, set-top boxes, displays, appliances, networking gear and gaming products.

InnoSwitch3 offline CV/CC flyback switcher ICs with PowiGaN technology are up to 95% efficient across the load range. The very low switching and conduction losses of PowiGaN’s primary switch allows the delivery of as much as 100W from a space-saving InSOP 24D surface-mount package in enclosed adapter applications without requiring a heat-sink. Quasi-resonant InnoSwitch3-CP, InnoSwitch3-EP and InnoSwitch3-Pro ICs combine the primary power switch, primary and secondary control with a safety isolated high-speed link (FluxLink) in between, as well as the secondary SR driver and feedback circuits in a single surface-mount package. Power Integrations says that the switching performance of PowiGaN technology results in substantially higher efficiency, enabling very compact adapter designs.

“Anker is a world leader in compact charger design, and was the first high-volume customer for InnoSwitch3 products with PowiGaN,” says Balakrishnan, who thanks Yang for his “critical contribution to the first successful mass-market deployment of high-voltage GaN technology.”

“By using PowiGaN-based InnoSwitch3 ICs we are able to offer USB PD chargers that are compact, lightweight and capable of delivering high power output,” comments Yang.
