Product Descriptions

The  XL1583  is  a  380KHz  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 PERCENT. An enable function,  an  over  current  protection  function     is built inside. When short protection function happens,   the   operation   frequency   will   be   reduced from 380KHz to 80KHz. An internal compensation  block  is  built  in  to  minimize  external component count.
