Controller IC Chip - NCP81038MNTWG NCP81038 81038 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0745) NCP81038 is a dual synchronous buck controller that is optimizedfor  converting  the  battery  voltage  or  adaptor  voltage  into  multiplepower  rails  required  in  desktop  and  notebook  system.  NCP81038consists of two buck switching controllers with fixed 5.0 V output onchannel  2,  3.3  V  on  channel  1  and  two  on−board  LDOs  with  threeoutputs: 5 V / 60 mA and 3.3 V or 12 V / 10 mA. NCP81038 supportshigh  efficiency,  fast  transient  response  and  provides  power  goodsignals.  ON  Semiconductor  proprietary  adaptive−ripple  controlenables seamless transition from CCM to DCM, where converter runsat reduced switching frequency with much higher efficiency at lightload.  The  part  operates  with  supply  voltage  ranging  from  5.5  V  to28 V. NCP81038 is available in a 28−pin QFN package. Wide Input Voltage Range: from 5.5 V to 28 V•Built−in 5 V / 60
