一、DESCRIPTION
XR8121 is a wide input range, high-efficiencyand high frequency DC-to-DC step-down switchingregulator, capable of delivering up to 2A ofoutput current. With a fixed switching frequency of1MHz, this current mode PWM controlled converterallows the use of small external components,such as ceramic input and output caps, as wellas small inductors. ETA8121 also employs aforced PWM control scheme, thereby ensuring theminimum ripple voltage. Its input can withstanda voltage surge as high as 30V, making it anideal solution for industrial applications suchas Surveillance Camera, LCD TV, Set Top Box,etc
