Renesas Electronics has developed a GaN-based half-bridge LLC resonant converter capable of 500W power delivery, targeting industrial and IoT equipment applications to improve efficiency and power density.
Context
On March 23, 2026, Renesas Electronics announced the development of a new 500W Gallium Nitride (GaN) based Half-Wave LLC (HWLLC) resonant converter, significantly expanding its power delivery capabilities for industrial and IoT applications. This new topology allows the company to scale its ultra-efficient power architecture from previous 100W-class designs up to 500W, targeting high-demand devices such as power tools, e-bikes, and large displays. By utilizing its proprietary SuperGaN technology, Renesas achieved a peak efficiency of 96.5% and an industry-leading power density of 3W/cc.
This development is a critical step in Renesas’ strategy to move beyond consumer electronics into the $9 billion industrial power supply market. By enabling the transition from proprietary 'brick' chargers to compact 240W USB EPR solutions, the company is addressing the growing need for high-efficiency, low-heat power conversion. The platform is already seeing commercial traction, with partners like Belkin integrating Renesas GaN technology into next-generation fast-charging hardware.
