220KHz 60V 5A Switching Current Boost / Buck-Boost / Inverting

DC/DC Converter                                                                      XL6019

General Description

    The  XL6019  regulator  is  a  wide  input  range, current mode,  DC/DC

converter  which  is  capable   of  generating  either  positive  or  negative

output v oltages.  It  can  be  configured  as either a boost, flyback, SEPIC

or  inverting  converter.  The  XL6019  built  in  N-channel  power MOSFET

and  fixed frequency oscillator,  current-mode architecture results in stable

operation over a wide range of supply and output voltages.

    The XL6019 regulator is special design for portable electronic equipment

applications.
