GENERAL DESCRIPTION
The CM8500 is a switching regulator designed to provide a
desired output voltage or termination voltage for various
applications by converting voltage supplies ranging from 2.0V
to 4.0V. The CM8500 can be implemented to produce
regulated output voltages in two different modes. In the
default mode, when the VIN/2 pin is open, the output voltage
is 50% of the VCCQ. The CM8500 can also be used to
produce various user-defined voltages by forcing a voltage on
the VIN/2 pin. In this case, the output voltage follows the
VIN/2 pin input voltage. The switching regulator is capable of
sourcing or sinking up to 3A of current while regulating an
output V
TT
voltage to within 3% or less.
The CM8500, 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.
