Power Integrations launches 1700 V GaN switcher IC
Power Integrations has introduced a new member of its InnoMux-2 family of single-stage, independently regulated multi-output offline power supply ICs. The new device features the industry’s first 1700 V gallium nitride switch, fabricated using the company’s proprietary PowiGaN technology. The 1700 V rating further advances the state-of-the-art for GaN power devices, previously set by Power Integrations’ own 900 V and 1250 V devices, both launched in 2023. The 1700 V InnoMux-2 IC easily supports 1000 VDC nominal input voltage in a flyback configuration and achieves over 90 percent efficiency in applications requiring one, two or three supply voltages. Each output is regulated within one percent accuracy, eliminating post regulators and further improving system efficiency by approximately ten percent. The new device replaces expensive silicon carbide (SiC) transistors in power supply applications such as automotive chargers, solar inverters, three-phase meters and a wide variety of industrial power systems.
