SF6XXX provides possibility for operating in QCW mode with the 

rise time 60μs without overshooting. 

Rise time differs from model to model.

Easy to place an order

Worldwide fast shipping

It is easy to get our driver anywhere in the world.   

We have distributors in     

10 countries and stock in USA and Korea.


Large stock

We have in stock most of the models. This allows us to provide lead time 2-4 days.


Quality control

Quality control is our most important goal. We test each driver and provide a test report. This allows us to provide a failure rate less than 1%.
