The most expensive components in the driver are the transformers.
In large volumes >100ku the transformer price will be app. 0.80 EUR each – each driver needs two transformers. The price is not negotiated, so it might be possible to drive the cost down even further. The remaining components for the driver will be at a price level of approximately 0.8 EUR.
The estimated total component prices per driver will be approximately 2.50 EUR for volumes above 100Ku. This is based upon the present design for the driver components, and there is no NRE needed to achieve this price.
