Advance Information
Synchronous Buck
Controller for High
Efficiency Post Regulation
The NCP4331 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. Directly fed by the secondary ac signal, the device
keeps power dissipation to the lowest while reducing external
component count. Further, the implementation of N-channel
MOSFETs gives NCP4331-based applications a significant advantage
in terms of efficiency.
