Hot-selling and scarce LM2676SDX-ADJ/NOPB Power Converter, High Efficiency, 3A, Step-DownVoltage Regulator 14VSON spot stock

Product Descriptions

The   LM2676  series  of  regulators   are   monolithicintegrated  circuits  which  provide  all  of  the  activefunctions for a step-down (buck) switching regulatorcapable of driving up to 3A loads with excellent lineand  load  regulation  characteristics .  High  efficiency(> 90%)  is obtained through the  use of a  low  ONresistance DMOS power switch . The series consistsof fixed output voltages of 3.3V, 5V, and 12V and anadjustable output version .

The power converter conceptprovides  for  a  complete  design  using  a  minimumnumber   of   external   components .   A   high   fixedfrequency   oscillator   (260kHz)   allows   the   use   ofphysically  smaller  sized  components .  A  family  ofstandard  inductors  for  use  with  the  LM2676  areavailable   from   several   manufacturers   to   greatlysimplify the design process .

The    LM2676   series   also    has    built-in   thermalshutdown,  current  limiting,  and  an  ON  and  OFFcontrol  input that  can  power  down the  regulator toa  low  50µA  quiescent  current  standby  condition .The output voltage is specified to a ±2% tolerance .The  clock frequency  is  controlled to within a  ±11%tolerance .
