We have published a white paper titled "A Comprehensive Explanation of 1700V GaN."

We have released the industry's only 1700V gallium nitride (GaN) switching power supply IC as part of the InnoMux-2 family of products, significantly expanding the applications of GaN technology. Two newly published white papers provide valuable insights into how 1700V GaN devices maximize efficiency and power density in multi-power flyback power supplies.

1700V GaN switch with adaptive zero-voltage switching for multi-output flyback converters
- Optimization of dual-output flyback efficiency and output regulation using 1700V GaN switches.

Power Integrations' PowiGaN technology, which enables 1700V ratings, has made it possible for GaN devices to replace expensive silicon carbide (SiC) transistors in demanding industrial applications such as three-phase meters and auxiliary power supplies for automotive chargers and solar inverters. The 1700V InnoMux-2 IC combines the benefits of four pioneering innovations from Power Integrations.

• 1700V PowiGaN Switch: Industry-leading voltage blocking capability of gallium nitride.
- InnoMux-2's multi-output function: Individual output control without the need for a subsequent regulator.
• One-chip zero-voltage switching: Minimizes switching losses without active clamping.
• FluxLink secondary regulation: Communication between isolation barriers without using photocouplers

The InnoMux-2 device allows system engineers to rethink power architectures and integrate DC-DC stages into the main power system. It delivers over 90% efficiency from a 1000VDC bus and provides up to 70W from three highly controlled outputs.
