FR9810 Overview
Description
FR9810 is a high-efficiency synchronous mode step-down DC/DC converter that employs a special process technique to obtain very low RDS(ON) for the internal metal–oxide–semiconductor field-effect transistor (MOSFET), with operation voltage in a wide 4.75V to 21V input voltage range. The output current is over 6A, and the efficiency is over 90%.
