/MPS MP2122 6V, 2A, Low Quiescent Current Dual, SYNC Buck Regulator

MPS MP2122 6V, 2A, Low Quiescent Current Dual, SYNC Buck Regulator

The   MP2122   is   an   internally-compensated,   1MHz fixed-frequency, dual PWM, synchronous, step-down   regulator.

    MPS
  • Product Details

DESCRIPTION 

The   MP2122   is   an   internally-compensated,   1MHz fixed-frequency, dual PWM, synchronous, step-down   regulator.   The   MP2122   operates   from  a  2.7V-to-6V  input,  generates  an  output  voltage  as  low  as  0.608V,  and  has  a  45μA  quiescent   current   that   makes   it   ideal   for   powering  portable  equipment  that  runs  on  a  single cell lithium-ion (Li+) battery. 

The  MP2122  integrates  dual  80mΩ  high-side  switches  and  35mΩ  synchronous  rectifiers  for  high   efficiency   without   an   external   Schottky   diode.  Peak-current  mode  control  and  internal  compensation  limits  the  minimum  number  of  readily-available external components. 

Fault-condition  protections  include  cycle-by-cycle  current limiting and thermal shutdown. 

The  MP2122  is  available  in  an  8-pin  TSOT23-8  package.
