What Can SuperQ® Do for Fast Chargers?
As device batteries for consumer electronics get larger, charging speed has become a top user demand. OnePlus reports that 43% of U.S. consumers are frustrated by slow charging, and Android Authority found fast charging is the feature users refuse to give up — even over display or camera quality.
With USB PD 3.1 pushing voltages to 48 V and power to 240 W, true fast charging is now possible across consumer devices.
SuperQ MOSFETs enable higher current per device, stronger transient tolerance, and lower thermal losses — making fast chargers more efficient, compact, and reliable.

SuperQ®
A New Class of Silicon Efficiency
iDEAL Semiconductor's SuperQ technology delivers a step change in performance by reinventing the silicon power switch - no exotic materials required.
Built on a high-aspect-ratio trench structure, SuperQ:
- Drives ~95% silicon utilization—nearly double conventional MOSFETs
- Achieves record-low RDS(on) per mm² and ultra-low switching loss
- Operates with significantly cooler junction temps
- Enables fast switching for high-frequency, compact chargers
- Uses a CMOS-compatible, cost x performance optimized manufacturing flow
Optimized for Modern Consumer Devices
SuperQ is ideal for:
- USB PD 3.1 charging adapters (180W-240W)
- Laptop and tablet chargers
- Smartphone fast-charging hubs
- Docking stations and PD-enabled accessories with integrated power delivery
