GENERAL DESCRIPTION
In the default mode, when the VREF pin is open, the ML6554 output voltage is 50% of the voltage applied to VCCQ. In this case, the output voltage follows the input VREFIN voltage. The switching regulator is capable of sourcing or sinking up to 3A of current while regulating an output VTT voltage to within 3% or less. The ML6554, 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 other bus interface standards such as SSTL, CMOS, Rambus™, GTL+, VME, LV-CMOS, LV-TTL, and PECL. FEATURES
