3V input supply.
Sipex's unique "AnyFETTM" Technology allows the SP6120B 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.
