AX3513   1.4MHz, 1A Synchronous Step-Down Converter

性能描述： 

        AX3513  is  a  high  efficiency  monolithic  synchronous  buck  regulator  using  a  constant
frequency,  current  mode  architecture.  The  device  is  available  in  an  adjustable  version.
Supply current with no load is 250uA and drops to <1uA in shutdown. The 2.5V to 5.5V input
voltage  range  makes  AX3513  ideally  suited  for  single  Li-Ion,  two  to  three  AA
battery-powered  applications.  100%  duty  cycle  provides  low  dropout  operation,  extending
battery  life  in  portable  systems.  PWM  operation  provides  very  low  output  ripple voltage  for
noise  sensitive  applications.  Switching  frequency  is  internally  set  at  1.4MHz,  allowing  the
use  of  *all  surface  mount  inductors  and  capacitors.  The  internal  synchronous  switch
increases efficiency and decreases need of an external schottky diode. Low output voltages
are easily supported with the 0.6V feedback reference voltage. AX3513 is available in *all
TSOT-23-5L and TDFN-6L packages.                      

特点： 
•  2.5V to 5.5V Input Voltage Range
•  Output Voltage from 0.6V to VIN
•  High Efficiency: Up to 96%
•  1.4MHz Constant Frequency Operation
•  Up to 1A Output Current 
•  Quiescent Current: 250uA (T*ical)
•  No Schottky Diode Required  
•  Current Mode Operation for Excellent Line and Load Transient Response
•  Current limit, Enable function
•  Short Circuit Protect (SCP)
•  Build in soft start function
•  ≤ 1µ A Shutdown Current
•  TSOT-23-5L and TDFN-6L Pb-Free packages
