Wise-integration launches compact 120mΩ GaN half-bridge power IC

Wise-integration of Meylan, France, which was founded in 2020 and specializes in the digital control of gallium nitride (GaN) power supplies and GaN integrated circuits, has launched its first commercial product: the 120mΩ WI62120 half-bridge power circuit, which is claimed 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 IC, 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 utilizing 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.

“The 120mΩ WI62120 is the most compact half-bridge in the market, with a 6x8 PQFN package that maximizes customer benefits in terms of high power density, performance, and bill-of-materials cost reduction,” claims CEO Thierry Bouchet. “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 says that, with its 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.
