Power Integrations, a provider of high-voltage integrated circuits for energy-efficient power conversion, has introduced a new product in its InnoMux-2 family of single-stage, independently controlled multi-offline power supply ICs.
The new device features a 1,700 V gallium nitride (GaN) switch, made using the company's PowiGaN technology and builds on the company's 900 V and 1,250 V devices launched in 2023.
The 1,700 V InnoMux-2 IC supports a 1,000 VDC flyback input voltage and achieves an efficiency of more than 90%, providing up to 70 W from three outputs.
Each output is controlled within 1% accuracy, eliminating post controllers and improving system efficiency by about 10%, according to the company. The device can replace silicon carbide (SiC) transistors in power supply systems such as car chargers, solar inverters, three-phase meters and various industrial power systems.
“Our new InnoMux-2 ICs include 1,700 V GaN and three other state-of-the-art innovations: independent, precise, multi-effect regulation; FluxLink, our digital separation communications technology for second-party control (SSR); and zero voltage switching (ZVS) without an active clamp, which all but eliminates switching losses,” said Radu Barsan, VP of technology at Power Integrations.
