DESCRIPTION  
The SP6120HV is a fixed frequency, voltage mode, synchronous PWM controller designed  
to work from a single 12V, 5V or 3.3V input supply. Sipex's unique "AnyFETTM" Technology  
allows the SP6120HV to be used for resolving a multitude of price/performance trade-offs.  
It is separated from the PWM controller market by being the first controller to offer precision,  
speed, flexibility, protection and efficiency over a wide range of operating conditions.
