GENERAL DESCRIPTION
   The XRP7720 is a quad output universal customizable PMIC comprised of a quad channel Digital Pulse Width Modulated (DPWM) Step down (buck) controller and 5V LDO. A wide 4.75V to 5.5V and 5.5V to 18V input voltage dual range allows for single supply operation from standard power rails. It is pin compatible to the popular XRP7724 and provides full flexibility during the development phase while offering a cost effective option for high volume production units.
