FEATURE DESCRIPTIONS (CON.)
The amount of power delivered by the module is the voltage at the output terminals multiplied by the output current. When using the trim feature, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module must not exceed the maximum rated power (Vo.set x Io.max ≤ P max).
Voltage Margining
Output voltage margining can be implemented in the DNL modules by connecting a resistor, R
The output voltage tracking feature (Figure 40 to Figure
42)is achieved according to the different external connections. If the tracking feature is not used, the TRACK pin of the module can be left unconnected or tied to Vin.
For proper voltage tracking, input voltage of the tracking power module must be applied in advance, and the remote on/off pin has to be in

By connecting multiple modules together, customers can get multiple modules to track their output voltages to the voltage applied on the TRACK pin.
