Controller IC Chip - NCP5901BMNTBG NCP5901B ( AZ* ) Chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0789) The  NCP5901B  is  a  high  performance  dual  MOSFET  gate  driveroptimized  to  drive  the  gates  of  both  high−side  and  low−side  powerMOSFETs in a synchronous buck converter. It can drive up to 3 nFload with a 25 ns propagation delay and 20 ns transition time.Adaptive   anti−cross−conduction   and   power   saving   operationcircuit can provide a low switching loss and high efficiency  solutionfor notebook and desktop systems. Bidirectional EN pin can providea  fault  signal  to  controller  when  the  gate  driver  fault  detect  underOVP,   UVLO   occur.   Also,   an   under−voltage   lockout   functionguarantees the outputs are low when supply voltage is low.
