     3A 150KHz 40V Buck DC to DC Converter     　　  XL1507

     General Description

       The XL1507 is a 150 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. When second current  limit function happens,

the operation frequency will be reduced from 150KHz  to  50KHz.  An

internal   compensation   block   is   built   in   to   minimize   external

component   count.

    Features  

  1） Wide 4.5V to 40V Input Voltage Range

  2） 5V and adjustable versions

  3） Output Adjustable from 1.23V to 37V

  4） Maximum Duty Cycle 100%

  5） Minimum Drop Out 1.5V

  6） Fixed 150KHz Switching Frequency
