The PTH08T255W module is capable of being configured in parallel with another PTH08T255W module to share
load current. To parallel the two modules, it is necessary to configure one module as the Master and one module
as the Slave. To configure a module as the Master, connect the CONFIG pin (pin 1) to GND. The CONFIG pin of
the Slave must be connected to VI. In order to share current, pins 2 thru 5 of both the Master and Slave must be
connected between the two modules. See Figure 22 for the recommended layout of pins 2 thru 5. The module
that is configured as the MASTER is used to control all of the functions of the two modules including Inhibit
ON/OFF control, AutoTrack sequencing, TurboTrans, SmartSync, +/- Remote Sense, and Output Voltage Adjust.
See the current sharing diagram in Figure 19 for connections. The MASTER and the SLAVE must be powered
from the same input voltage supply.
See Figure 19 and Table 7 for a diagram and connection description of each pin when two PTH08T255W
modules are being used in a MASTER/SLAVE configuration.
