Power Integrations IMX2353F InnoMux2-EP 1700 V GaN Switcher IC Power Essentials

Power Integrations IMX2353F incorporates the industry’s first 1700 V gallium-nitride (GaN) power switch and uses a zero-voltage-switching (ZVS) flyback architecture.

Power Integrations IMX2353F is a highly integrated offline flyback switcher IC in the InnoMux‑2 EP family that incorporates the industry’s first 1700 V gallium-nitride (GaN) power switch, establishing a new voltage benchmark for GaN technology. Built on the company’s PowiGaN technology, the device integrates a high-voltage GaN switch, control circuitry, and multi-output regulation into a single IC, enabling direct operation from high-voltage DC buses up to about 1000 V. The IC uses a zero-voltage-switching (ZVS) flyback architecture with FluxLink digital isolation feedback to eliminate optocouplers while maintaining reinforced isolation. Designed for industrial and energy-infrastructure applications, it supports up to three independently regulated outputs with up to 100 W continuous power, demonstrating how high-voltage GaN devices can extend beyond traditional 650–900 V ranges and compete with silicon-carbide (SiC) solutions in high-voltage power supplies.
