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
even under variable or light load conditions.
Note: 1) The S GND pins of each module must also be connected together to ensure accurate current sharing.
