Current Sharing (C SHARE)
To ensure that all modules in a parallel system accurately
share current, the C SHARE pins on each module should
be connected together.
The voltage on the C SHARE pins represents the average
load current per module. Each module compares this
average with its own current and adjusts its output voltage
to correct the error. In this way the module maintains
accurate current sharing.
Note: The -SENSE and +SENSE pins of each module must
also be connected together to ensure accurate current
sharing.
Current Monitoring (C MON)
The C MON pin provides an indication of the amount of
current supplied by the module. The output of the C MON
pin is a current source proportional to the

The C MON output can be paralleled with C MON outputs
from other modules to indicate the total current supplied in a
paralleled system.
Temperature Monitoring (TEMP
MON)
The TEMP MON pin provides an indication of the
module's internal temperature.The voltage at the TEMP
MON pin is proportional to the temperature of the module
baseplate at 10mV per °C, where:
The temperature monitor signal can be used by thermal
management systems (e.g. to control a variable speed fan).
It can also be used for overtemperature warning circuits
and for thermal design verification of prototype power
supplies and heatsinks.
