Features                                               General Description
 Wide 4.5V to 40V Input Voltage Range                  The   XL2576     is  a  52  KHz  fixed  frequency
 3.3V,5V,12V and adjustable versions                   PWM      buck   (step-down)   DC/DC     converter,
 Output Adjustable from 1.23V to 37V                   capable    of  driving   a  3A   load   with  high
 Maximum Duty Cycle 100%                               efficiency,   low   ripple   and   excellent   line   and
 Minimum Drop Out 1.5V                                 load    regulation.    Requiring    a   minimum
 Fixed 52KHz Switching Frequency                       number of external components, the regulator
 3A Constant Output Current Capability                 is   simple    to   use   and   include    internal
 Internal Optimize Power Transistor                    frequency         compensation         and        a
 High efficiency                                       fixed-frequency oscillator.
 Excellent line and load regulation
 TTL shutdown capability
                                                       The PWM control circuit is able to adjust the
 ON/OFF pin with hysteresis function
 Built in thermal shutdown function                    duty ratio linearly from 0 to 100%. An enable
 Built in current limit function                       function,   an   over   current   protection   function
 Available in TO-220,TO-263 packages                   is   built  inside.  An   internal  compensation
                                                       block    is  built   in  to   minimize    external
                                                       component count.
