Controller IC Chip – MAX17491GTA MAX17491 17491 BMH chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0669) The  MAX17491  is  a  single-phase  synchronous  nonin-verting  MOSFET  driver.  The  MAX17491  is  intended  towork  with  controller  ICs  like  the  MAX8736,  MAX8786,  orMAX17030 in multiphase notebook CPU core regulators.The  regulators  can  either  step  down  directly  from  thebattery  voltage  to  create  the  core  voltage  or  step  downfrom  the  main  system  supply.  The  single-stage  conver-sion method allows the highest possible efficiency, whilethe  2-stage  conversion  at  higher  switching  frequencyprovides the minimum possible physical size.The low-side driver is optimized to drive 3nF capacitiveloads  with  4ns/8ns  typical  fall/rise  times,  and  the  high-side driver with 8ns/10ns typical fall/rise times.Adaptive dead-time control prevents shoot-through cur-rents and maximizes converter efficiency.The  MAX17491  features  improved  zero
