高压降压转换器Buck_TP3320_深圳市利盛达科技有限公司

DESCRJPTION  ：3A同步高压降压DC-DC
The  TP3320  is  a  500KHz  fixed  frequency  synchronous  current  mode  buck  regulator.  The  device  integrates  both  135m?    high-side  switch  and  90m  ?  low-side  switch  that  provide  3A  of  continuous  load  current  over  a  wide  operating  input  voltage  of  4.5V  to  28V.  The  internal  synchronous  power  switch  increases  efficiency  and  eliminates  the  need  for  an  external  Schottky  diode.Current  mode  control  provides  fast  transient  response  and  cycle-by-cycle  current  limit.
The  TP3320  features  short  circuit  and  thermal  protection  circuits  to  increase  system  reliability.  Externally  programmable  soft-start  allows  for  proper  power  on  sequencing  with  respect  to  other  power  supllies  and  avoids  input  inrush  current  during  startup.In  shutdown  mode,  the  supply  current  dropsbelow  1µA.TheTP3320isavailable  in  SOP-8  package  with  the  exposed  pad.
