Controller IC Chip - MAX1902E MAX1902EA MAXI902 MAX19O2 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0672) The  MAX1901/MAX1902/MAX1904  are  buck-topology,step-down,  switch-mode,  power-supply  controllers  thatgenerate  logic-supply  voltages  in  battery-powered  sys-tems. These high-performance, dual/triple-output devicesinclude on-board power-up sequencing, power-good sig-naling  with  delay,  digital  soft-start,  secondary  windingcontrol, low dropout circuitry, internal frequency-compen-sation networks, and automatic bootstrapping.Up  to  97%  efficiency  is  achieved  through  synchronousrectification  and  Maxim’s  proprietary  Idle  Mode™  controlscheme.  Efficiency  is  greater  than  80%  over  a  1000:1load-current  range,  which  extends  battery  life  in  systemsuspend  or  standby  mode.  Excellent  dynamic  responsecorrects  output  load  transients  within  five  clock  cycles.Strong  1A  on-board  gate  drivers  ensure  fast  external  N-chann
