Features                                               General Description
Wide 4.5V to 40V Input Voltage Range                  The   XL1509   is   a   150   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 2A   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 150KHz Switching Frequency                      number of external components, the regulator
2A 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
                                                       is   built inside. When   second    current limit
