Power Integrations announced the delivery of its one-millionth InnoSwitch3 switcher IC featuring the company’s PowiGaN gallium-nitride technology. In an event at the Shenzhen headquarters of Anker Innovations, Power Integrations CEO Balu Balakrishnan presented the one-millionth GaN-based IC to Anker CEO Steven Yang. Anker is a leading manufacturer of chargers and adapters, supplying retailers worldwide with powerful, compact USB PD adapters and a wide 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. Very low switching and conduction losses of PowiGaN primary switch allows delivery of as much as 100 W from a space saving InSOP 24D surface mount package in enclosed adapter applications without requiring a heatsink. Quasi-resonant InnoSwitch3-CP, InnoSwitch3-EP and InnoSwitch3-Pro ICs combine the primary power switch, primary and secondary control with safety isolated high-speed link (FluxLink) in between, as well as the secondary SR driver and feedback circuits in a single surface-mounted package. The superior switching performance of PowiGaN technology results in substantially higher efficiency, enabling very compact adapter designs.
Power Integrations’ new InnoSwitch3 ICs are available now, priced at $4/unit in 10,000-piece quantities. Technical information on PowiGaN-based products – along with five new reference designs describing USB PD chargers from 60 W to 100 W – are available on the Power Integrations website at: www.power.com/PowiGaN.
