Richtek RT9173BGS

转换器，DDR 总线端接稳压器1.7V ~ 6V可调式

Overview

The RT9173BGS regulator is designed to convert voltage supplies ranging from 1.7V to 6V into a desired output voltage of which adjusted by two external voltage divider resistors. The regulator is capable of sourcing or sinking up to 2A of current while regulating an output voltage to within 40mV.The RT9173B, used in conjunction with series termination resistors, provides an excellent voltage source for active termination schemes of high speed transmission lines as those seen in high speed memory buses and distributed backplane designs. The voltage output of the regulator can be used as a termination voltage for DDR SDRAM.Current limits in both sourcing and sinking mode, plus on-chip thermal shutdown make the circuit tolerant of the output fault conditions.The RT9173BGS are available in the popular 5-lead TO-252 and fused SOP-8 (the multiple VCNTL pins on the SOP-8 package are internally connected but lowest thermal resistance) surface mount packages.
