Product Description

Silicon MOS is a new type of silicon-based material that offers significant advantages in terms of density, thermal conductivity, and efficiency conversion. Thanks to the use of super silicon black technology, chargers made with this material can be smaller in size and charge devices at a faster rate. Even under high temperature conditions, they remain safe and stable.

Furthermore, super silicon has extremely low driving loss and switching loss, making it highly efficient, especially at a higher frequency of 400KHz. In fact, its efficiency is comparable to that of GaN power devices.
