Richtek RT9173CPSP

转换器，DDR 总线端接稳压器1.5V ~ 2.5V多重

Overview

The RT9173/A regulator is designed to convert voltage supplies ranging from 1.6V to 6V into a desired output voltage which adjusted by two external voltage divider resistors. The regulator is capable of sourcing or sinking up to 3A of peak current while regulating an output voltage to within 2% (DDR 1) and 3% (DDR 2) or less. The RT9173/A, 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.
