Controller IC Chip - MAX8632ETI MAX8632E 8632E chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0677) The  MAX8632  integrates  a  synchronous-buck  PWM  con-troller to generate VDDQ, a sourcing and sinking LDO lin-ear  regulator  to  generate  VTT,  and  a  10mA  referenceoutput buffer to generate VTTR. The buck controller drivestwo external n-channel MOSFETs to generate output volt-ages down to 0.7V from a 2V to 28V input with output cur-rents  up  to  15A.  The  LDO  can  sink  or  source  up  to  1.5Acontinuous  and  3A  peak  current.  Both  the  LDO  outputand  the  10mA  reference  buffer  output  can  be  made  totrack the REFIN voltage. These features make theMAX8632  ideally  suited  for  DDR  memory  applications  indesktops, notebooks, and graphic cards.The  PWM  controller  in  the  MAX8632utilizes  Maxim’sproprietary  Quick-PWM™  architecture  with  programma-ble  switching  frequencies  of  up  to  600kHz.  This  controlscheme  handles  wide  input/outpu
