CM8500A

3A BUS TERMINATOR

GENERAL DESCRIPTION

FEATURES

◆

Patent Filed #6,452,366

pin PTSSOP and PSOP package

The CM8500A 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 5.0V. The CM8500A can be implemented to produce

regulated output voltages in two different modes. In the

Source and sink up to 3A, no heat sink required

Peak Current to 6A

Integrated Power MOSFETs

Output voltage can be programmed by external resistors

Separate voltages for VCCQ and PVDD

V OUT of ±3% or less at 3A

default mode, when the VIN/2 pin is open, the output voltage

is 50% of the VCCQ. The CM8500A can also be used to

Minimum external components

produce various user-defined voltages by forcing a voltage on

the VIN/2 pin. In this case, the output voltage follows the

Shutdown for standby or suspend mode operation

Thermal shutdown protection

VIN/2 pin input voltage. The switching regulator is capable of

sourcing or sinking up to 3A of current while regulating an

output V _TTvoltage to within 3% or less.

6A Low Noise Current Limit Protection

External Soft Start

Rail to Rail output Buck Converter

The CM8500A, 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.

APPLICATIONS

PCI / AGP Graphics

Game / Play Station

Set Top Box

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.
