Description
The SC4524D is a constant frequency peak current-mode step-down switching regulator capable of producing 2A output current from an input ranging from 3V to 18V. The switching  frequency  of  the  SC4524D  is  programmable up  to  2MHz,  allowing  the  use  of  small  inductors  and ceramic  capacitors  for  miniaturization,  and  high  input/output  conversion  ratio.  The  SC4524D  is  suitable  for next  generation  XDSL  modems,  high-definition TVs  and various point of load applications.
