Wise-integration Launches Compact GaN Half-Bridge Power IC

News

WI62120 gives power electronics designers new density, performance, efficiency options

Wise-integration, a company focused on digital control of GaN power supplies and GaN ICs, has launched it first commercial product: the 120mOhm WI62120 half-bridge power circuit, which is said to provide power electronics designers with new levels of power density, performance, and cost-effectiveness.

The JEDEC-certified WI62120, a 650V enhancement mode GaN-on-silicon integrated circuit, is part of Wise-integration's WiseGan family of power devices. It leverages the intrinsic properties of GaN to provide improved current capabilities, voltage breakdown, and switching frequencies for applications in high-efficiency and high-density power conversion, including AC/DC, DC/DC, and DC/AC, from 30W to 3kW.

Target market sectors include consumer (such as ultra-fast chargers for mobile and desktop devices), E-mobility, and industrial AC/DC power supplies and designs using Bridgeless Totem Pole power factor conversion (PFC) active clamp flyback (ACF), two-inductor one-capacitor (LLC) resonant converters, and synchronous buck or boost half-bridge topologies.

“We are proud to bring our first WiseGan product release into production,” said Thierry Bouchet, CEO of Wise-integration. “The 120 mOhm WI62120 is the most compact half bridge in the market with a 6x8 PQFN package that maximises customer benefits in terms of high power density, performance, and bill of materials cost reduction. We're confident that our customers will find it very useful in all ACF topologies and PFC-LCC architectures, and that it will help them leverage the benefits provided by smaller, more-efficient, and more cost-effective power electronics."

Wise-integration extends the advantages of GaN with WiseWare embedded digital control software; subsequent generations of WiseGan devices will integrate functions such as gate control, protection, security, and other designer-friendly capabilities into AC/DC GaN applications.
