»View Reliability Data »View Material Composition »Product Change Notification (1)

The NCP4330 houses a dual MOSFET driver intended to be used as a companion chip in AC−DC or DC−DC multi−output post regulated power supplies. Being directly fed by the secondary AC signal, the device keeps power dissipation to the lowest while reducing the surrounding part count. Furthermore, the implementation of a N−channel MOSFET gives NCP4330−based applications a significant advantage in terms of efficiency.
