Additionally, when the power draw is below a certain threshold, the charger shifts to a higher efficiency mode to further maximise performance and reduce energy loss.
Available now through GaN Systems, the charger reference design includes prototypes and documentation (schematics, PCB layout, BOM, and design guideline) to shorten design cycles and speed up product launches.
The 100W charger reference design uses GaN Systems’ GS-065-011-1-L transistor for outstanding performance with the following key features:
- Ultra-high-power density: more than 16W/in3 with case and foldable prong
- Flexible and smart power distribution: Dual USB-C ports to support universal USB-C protocols and flexible plug-in end devices
- Peak Efficiency: more than 92.5%,
- Exceeds EN55032 Class B with more than 6dB margin
- Meets safety IEC62368-1 touch temperature requirement
- Meets IEC61000-3-2 for power line harmonics with Power Factor Correction (PFC) circuit
“Consumers have spoken, and they want GaN chargers. 65 watts was the start and now everyone wants 100 watts and multiple ports,” said Jim Witham CEO of GaN Systems, “Our design, validated by leading customers, is the highest performance, smartest, and smallest charger design that gets customers’ products to market in record time.”
