GaN Chagers VS Traditional Chargers Do you know the differences between GaN chargers and traditional chargers? 🌈GaN chargers offer higher output power, typically reaching 65W. This means they can not only charge your phone but also power your laptop. 🌈GaN are compact—about one-third the size of traditional laptop chargers—making them incredibly convenient to carry around. 🌈GaN chargers are generally more expensive than traditional chargers. But what exactly is GaN? How does it allow for higher output power while also reducing the charger’s size? The key difference between traditional and GaN chargers lies in the type of switching transistor used. Traditional chargers typically use MOSFETs as their switch, while GaN chargers use GaN transistors. When GaN transistors are used, it allows for the use of a thinner transformer. MOSFETs, which are used in traditional chargers, have a high parasitic capacitance, which limits the switching frequency. As a result, chargers using MOSFETs can typically only reach a switching frequency of around 150kHz. Any higher, and the heat generated would exceed safe levels. On the other hand, GaN transistors have much lower parasitic capacitance, allowing for much higher switching frequencies. The higher the switching frequency, the smaller the transformer can be. This is why GaN chargers can use slimmer transformers. Combined with the stacked and optimized design of other components, GaN chargers manage to maintain high output power while being much smaller in size. hashtag #GaNcharger #fastcharger #65Wcharger #wallcharger #phonecharger
