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).  
Table 1 provides Rtrim values required for some common  
output voltages, while Table 2 provides values of external  
voltage source, Vtrim, for the same common output  
voltages. By using a 1% tolerance trim resistor, set point  
tolerance of ±2% can be achieved as specified in the  
electrical specification.

Rtrim (K)  
Open  
Output voltage margining can be implemented in the DNL  
modules by connecting a resistor, R margin-up, from the Trim  
pin to the ground pin for margining-up the output voltage  
and by connecting a resistor, Rmargin-down, from the Trim pin  
to the output pin for margining-down. Figure 26 shows  
the circuit configuration for output voltage margining. If  
unused, leave the trim pin unconnected. A calculation  
tool is available from the evaluation procedure which  
computes the values of Rmargin-up and Rmargin-down for a  
specific output voltage and margin percentage.

Voltage Tracking  
The DNL family was designed for applications that have  
output voltage tracking requirements during power-up  
and power-down. The devices have a TRACK pin to  
implement three types of tracking method: sequential  
start-up, simultaneous and ratio-metric. TRACK simplifies  
the task of supply voltage tracking in a power system by  
enabling modules to track each other, or any external  
voltage, during power-up and power-down.  
By connecting multiple modules together, customers can  
get multiple modules to track their output voltages to the  
voltage applied on the TRACK pin.
