AccuPower™ FPF270x:

2.8V-36V, 0.4A-2A Advanced Integrated Load Switches
Fairchild’s Offering
Fairchild’s FPF270x AccuPower™ family of integrated load switches supports the latest generations of industrial,
telecom, computing and consumer devices. FPF270x is the first advanced integrated load switch to operate up to
36VIN, where traditional load switches typically operate up to 20VIN. The AccuPower family combines conventional
MOSFET performance with a unique combination of protection, control and fault monitoring features to enhance
and allow a faster time-to-market for end applications. The level of integration provides accurate, efficient and
reliable protection while minimizing the amount of board space requirements.
