Overcome density and efficiency challenges with MasterGaN
Advanced power system engineered to meet tomorrow’s high-voltage demands
As automation, digitalization, and renewable energy become pivotal across industries, the demand for efficient and reliable uninterruptible power supply (UPS) systems continues to grow rapidly. This trend drives the need for higher power density and efficiency to manage extreme thermal loads while ensuring long‑term reliability. ST’s advanced MasterGaN6 and MasterGaN7 SiPs integrate two GaN transistors and an enhanced gate driver in a compact package, delivering higher efficiency and power density while simplifying PCB layout. Dedicated pins for fault indication and standby further help optimize energy efficiency, thermal performance, and system robustness in next‑generation UPS designs.
