A new power MOSFET generation designed for synchronous rectification

Low-voltage MOSFETs are widely used in the synchronous rectifying stages of power supplies. To allow a high efficiency in light-load conditions, the power MOSFET not only needs to meet general requirements like low on-resistance, low gate charge and good avalanche capability, but must also have a low output capacitance and low reverse-recovery charge. The paper shows how those requirements were met in our newest generation of power MOSFET starting with the 60 V class.
