TF-EE19-2002-12.5 Transformer Enables 60W GaN Chargers in Pocket-Sized Designs
Title: "Gallium Nitride Revolution: 800×800mm Transformer Powers World's Smallest 60W Adapter"
The TF-EE19-2002-12.5 transformer is catalyzing a consumer electronics revolution. Its 12.5:1 voltage ratio and 200kHz operation enabled Anker to create a 60W GaN charger smaller than a golf ball (42×42×22mm). Test data shows:
92% peak efficiency at 20V/3A output
40°C temperature reduction vs. traditional designs
50% lower audible noise
Manufacturing breakthroughs include:
Automated helical winding for ±0.01% tolerance
Ferrite core with 230mT saturation flux density
100% automated optical inspection (AOI)
With Xiaomi and Samsung reportedly developing foldable phone chargers using this technology, industry analysts predict 300 million unit shipments by 2025.
