High Output Power Capability of Vishay’s SIC46X Family

In systems requiring step-down conversion from a high voltage of 24 V to 48 V bus at high power, a 60 V controller paired with discrete 80 V MOSFETs are typically used, especially when power levels exceed the 20 W range. This is mainly because even the best BCD processes cannot offer high performance MOSFETs in the 60 V to 80 V range.
