FEATURES DESCRIPTIONS (CON.)  
For example, to program the output voltage of the DNL  
module to 3.3Vdc, Rtrim is calculated as follows:  
Over-Temperature Protection  
10500  
The over-temperature protection consists of circuitry  
that provides protection from thermal damage. If the  
temperature exceeds the over-temperature threshold  
the module will shut down. The module will try to restart  
after shutdown. If the over-temperature condition still  
exists during restart, the module will shut down again.  
This restart trial will continue until the temperature is  
within specification  
Rtrim :=  
1000 ⋅Ω  
2.5475  
Rtrim = 3.122 k  
DNL can also be programmed by applying a voltage  
between the TRIM and GND pins (Figure 25). The  
following equation can be used to determine the value of  
Vtrim needed for a desired output voltage Vo:  
Remote Sense  
(
)
Vtrim := 0.7 Vo 0.7525 0.0667  
The DNL provide Vo remote sensing to achieve proper  
regulation at the load points and reduce effects of  
distribution losses on output line. In the event of an open  
remote sense line, the module shall maintain local sense  
regulation through an internal resistor. The module shall  
correct for a total of 0.1V of loss. The remote sense line  
impedance shall be < 10.  
Vtrim is the external voltage in V  
Vo is the desired output voltage

module to 3.3 Vdc, Vtrim is calculated as follows

Output Voltage Programming  
Figure 24: Circuit configuration for programming output voltage  
using an external resistor  
The output voltage of the DNL can be programmed to any  
voltage between 0.75Vdc and 5.0Vdc by connecting one  
resistor (shown as Rtrim in Figure 24) between the TRIM  
and GND pins of the module. Without this external  
resistor, the output voltage of the module is 0.7525 Vdc.  
To calculate the value of the resistor Rtrim for a particular  
output voltage Vo, please use the following equation:

Rtrim :=  
1000 ⋅Ω  
Vo 0.7525
