Silicon’s Reign is over

For more than four decades, silicon has been the foundation of modern electronics. Since the 1980s, it has powered everything from computers to chargers—offering an affordable, reliable way to conduct electricity more effectively than older materials.

Over the years, silicon-based components have become smaller, faster, and more efficient. But as technology pushes the limits of what’s possible, silicon is beginning to reach its physical boundaries.

The Limitations of Silicon

Silicon’s main constraint lies in its thermal and electrical transfer limits. Engineers just can’t make components smaller or any better at head efficient to match increasing charging demands.

In other words, we’ve squeezed almost all the performance we can out of silicon.

Enter GaN – The Next Generation of Power

Gallium Nitride (GaN) is a crystal-like semiconductor material that’s redefining power technology. Unlike silicon, GaN can handle much higher voltages, allowing electricity to flow faster and more efficiently.

This means less energy loss, less heat, and more power in a smaller space. The result? Smaller, lighter, and more powerful devices that stay cool and perform better.

In short: GaN is smaller, faster, cooler, and more efficient—making it ideal for modern, high-power applications like fast-charging devices.

The Proven History of GaN

GaN isn’t new. It was first used in the 1990s for LED lighting and has since been applied in high-performance technologies such as satellite solar panels and aerospace systems.

Benefits of GaN Technology

  • Higher Efficiency: GaN generates less heat than silicon, reducing wasted energy.
  • Compact Design: Lower heat allows components to be packed closer together, enabling smaller, lighter chargers.
  • High Power, Safely: Despite their small size, GaN chargers meet strict safety standards while delivering impressive wattage.
  • Portable Power: Chargers delivering 65W, 100W, or even 200W can now fit in a pocket-sized form factor—something previously impossible with silicon.

For example, a 100W GaN charger can be the same size as a traditional 30W silicon charger—delivering more power, faster, in less space.

Current industry Fast-Charging protocols

Modern fast chargers—especially GaN chargers—use smart charging protocols to safely deliver power at high speeds.

These include:

  • USB Power Delivery (USB-PD)
  • PPS
  • Qualcomm Quick Charge.

They all serve the same purpose: to let your device draw more power, safely and efficiently, than standard USB charging.

Here’s how each one works:

1.      USB Power Delivery™ (USB-PD™)

  • What it is: A universal standard for fast-charging USB devices.
  • How it works: Dynamically adjusts voltage and current to suit your device.
  • Key benefit: Charges a wide range of devices—phones, tablets, and laptops—with maximum efficiency.
  • Example: A USB-PD™ charger can deliver 5V, 9V, 12V, or 20V, depending on what your device requests.

2. Programmable Power Supply™ (PPS™ – part of USB-PD™ 3.0)

  • What it is: A more advanced version of USB-PD™ that fine-tunes voltage in real time.
  • How it works: The charger and device communicate constantly to match voltage precisely.
  • Key benefit: Higher efficiency and cooler charging, perfect for modern smartphones.
  • Example: Samsung™ Super Fast Charging uses PPS™ for safe, ultra-fast charging.

3. Qualcomm® Quick Charge™

  • What it is: Qualcomm’s proprietary fast-charging technology for Snapdragon®-powered devices.
  • How it works: Boosts voltage and current to deliver rapid charging safely.
  • Key benefit: Can charge compatible phones from 0–50% in just 15–30 minutes.
  • Versions:
    • QC™ 1.0: Early fast charging with limited efficiency.
    • QC™ 2.0 & 3.0: Faster, safer voltage management.
    • QC™ 4.0 / 4.0+: Compatible with USB-PD™, offering better efficiency and heat control.
    • QC™ 5: The latest standard—supports up to 100W+ charging, runs cooler, and is backward compatible with previous versions.

⚡ Note: Quick Charge™ only works with devices that support Qualcomm®’s standard.
