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

     General Description

    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.
