NCP4330
Post Regulation Driver
The NCP4330 houses a dual MOSFET driver intended to be used as
a companion chip in ACDC or DCDC multioutput 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
Nchannel MOSFET gives NCP4330based applications a significant
advantage in terms of efficiency.
