We have introduced the industry's first 1700V Gallium Nitride (GaN) switch as a new member of our InnoMux-2 IC family, greatly expanding the range of applications for GaN technology. InnoMux-2 devices enable the design of single-converter flyback power supplies with up to three independent outputs.

The achievement of the 1700V rating in Power Integrations' PowiGaN technology marks a watershed moment in the evolution of GaN power electronics, enabling GaN devices to replace expensive silicon carbide (SiC) transistors in three-phase meters and industrial applications such as auxiliary power in car chargers and solar inverters. The new ICs easily support supplies with a nominal voltage of 1000V DC and deliver 90% efficiency at up to 100W.

The following evaluation kits are now available to order:

RDK-1053 – 60W flyback converter with two independently controlled outputs

・Efficiency at full load is 90%
・DC 70V to DC 1000V input
5V / 2.5A and 24V / 2A outputs, each controlled to an accuracy of ±1%
・Output voltage protection without the need for a photocoupler for protection circuit
