Low Voltage GaN – Powering High Voltage Applications

Smaller. Cooler. Smarter.

Unlock ultra-efficient, compact AC/DC power conversion with the EPC91110 and EPC91107 demo boards. Designed with low-voltage GaN FETs, these solutions deliver higher power density and lower losses than silicon — making data center power smaller, lighter, and more efficient.

Why Low-Voltage GaN for AC/DC?

  • Higher Efficiency: Reduced switching and conduction losses for cooler operation.
  • Smaller Size: High-frequency operation shrinks magnetics and overall footprint.
  • Lower Cost
