DESCRIPTION

FEATURES

The EZ1900 is a high performance positive load cur-

rent balancer designed for use in applications utiliz-

ing 2 regulators in parallel to achieve equal current

sharing or identical current for each load. The regula-

tor balance controller allows a flexible motherboard

design to be made to cope with different processor

configurations. The controller reads a logic level up-

grade signal (denoted V_CC2DETon the Intel P55C; sim-

ilar on AMD, Cyrix and PowerPC microprocessors) to

control the output voltage of two linear low dropout

voltage regulators to the CPU core and I/O planes. In

single-voltage plane configurations (V_CC2DETfloating),

both regulators are set to the same output voltage

(usually 3.3 - 3.5V) and are configured in master-

slave mode. For split plane processors (V_CC2DETlow),

the outputs of the two regulators are switched - the

core voltage will be set to a nominal 2.5V while the

I/O voltage will remain at 3.3V. The actual output

voltages can be adjusted by means of resistors. The

EZ1900 programmable current balancer is available

in the popular SO-8 surface mount package.

Slave Mode Pin: For non “Computer Select Operation”, the Select

Mode, pin #1, can be left open circuited for continuous slave mode

operation or balance current control. Ground the Select Mode, pin #1,

for non-slave mode operation.
