Controller IC Chip - MOSFET G5316RZ1D G5316 5316 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0448) Complete  DDR2,  DDR3  and  DDR3L  Memory    Solution  Synchronous  Buck  PWM  Controller,    2A LDO, Buffered Reference The  G5316  is  intended  for  DDR2,  DDR3  and  DDR3L  memory  systems.  It  integrates  a  synchronous  buck  PWM controller with a 2-A sink-source linear regulator and buffered reference. The  PWM  controller  uses  constant  on-time  control  scheme to handle wide input/output voltage ratios with ease  and  provides  100ns  “instant-on”  response  to  load  transients  while  maintaining  a  relatively  constant  switching  frequency.  The  G5316  achieves  high  effi-ciency   at   a   reduced   cost   by   eliminating   the   cur-rent-sense  resistor  found  in  traditional  current-mode  PWMs.  Efficiency  is  further  enhanced  by  an  ability  to  drive  very  large  synchronous  rectifier  MOSFETs.  Sin-gle-stage  buck  conversion  allows
