XL2576  3A 52KHz 40V Buck DC to DC Converter

性能描述：
     The  XL2576  is  a  52  KHz  fixed  frequency PWM  buck  (step-down)  DC/DC  converter, capable  of  driving  a  3A  load  with  high efficiency, low ripple and excellent line and load  regulation.  Requiring  a  minimum number of external components, the regulator is  simple  to  use  and  include  internal frequency  compensation  and  a fixed-frequency oscillator. 
 
      The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is  built  inside.  An  internal  compensation block  is  built  in  to  minimize  external component count

特点：

·  Wide 4.5V to 40V Input Voltage Range
·  3.3V,5V,12V and adjustable versions 
·  Output Adjustable from 1.23V to 37V 
·  Maximum Duty Cycle 100% 
·  Minimum Drop Out 1.5V 
·  Fixed 52KHz Switching Frequency 
·  3A Constant Output Current Capability 
·  Internal Optimize Power Transistor 
·  High efficiency 
·  Excellent line and load regulation 
·  TTL shutdown capability 
·  ON/OFF pin with hysteresis function 
·  Built in thermal shutdown function 
·  Built in current limit function 
·  Available in TO-220,TO-263 packages
