Power Integrations, a provider of high-voltage integrated circuits for energy-efficient power conversion, 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 first 1700-V gallium nitride switch, fabricated using the company’s proprietary PowiGaN technology. The 1700-V rating further advances the high-efficiency and reliability of GaN power devices.
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 with one percent accuracy, eliminating post regulators and improving system efficiency by approximately ten percent.
The new device replaces expensive silicon carbide (SiC) transistors in power supply applications, such as automotive chargers and various industrial power systems.
