/MPS MP2143DJ-LF-Z 3A, 5.5V, 1.2MHz, 40μA IQ, COT Synchronous Step Down Switcher

MPS MP2143DJ-LF-Z 3A, 5.5V, 1.2MHz, 40μA IQ, COT Synchronous Step Down Switcher

The MP2143 is a monolithic, step-down, switch-mode  converter  with  internal  power  MOSFETs.

  • Brand:

    MPS
  • Product Details

DESCRIPTION 

The MP2143 is a monolithic, step-down, switch-mode  converter  with  internal  power  MOSFETs.  It   can   achieve   up   to   3A   continuous   output   current  from  a  2.5V–to-5.5V  input  voltage  with  excellent  load  and  line  regulation.  The  output  voltage can be regulated as low as 0.6V. 

Constant-on-time control provides fast transient response  and  eases  loop  stabilization.  Fault-condition    protections    include    cycle-by-cycle    current limiting and thermal shutdown.  

The  MP2143  is  available  in  small  TSOT23-8  package and requires only a minimal number of readily-available standard external components. 

The   MP2143   is   ideal   for   a   wide   range   of   applications  including  high-performance  DSPs,  FPGAs,   smartphones,   portable   instruments,   and DVD drivers.
