NCP4331 Description
NCP4331 Synchronous Buck Controller for High Efficiency Post Regulation The NCP4331 houses a dual MOSFET driver intended to be used as a panion 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 ponent count. Further, the implementation of N-channel MOSFETs gives NCP4331-based...
