For DNM12xx and DNL12xx series

Vtrim = 0.7 − 0.0667 ⋅ (Vout − 0.7525) V

For example, to program the output voltage of a DNL12 module to 3.3 Vdc, Vtrim is calculated as follows:

Vtrim = 0.7 − 0.0667 ⋅ (3.3 − 0.7525) = 0.53 V

8.2.5 Voltage Margining

Output voltage margining can be carry out by connecting a resistor from the Trim pin to ground pin for trim up and connecting a resistor from Trim pin to Output pin for Trim down. The Rmargin- up is for trim up and Rmargin-down is for trim down. (Please refer to the data sheet and Evaluation Board Schematic for the detailed information).

A software tool for voltage margining calculation is available to ask for. The values of Rmargin- up and Rmargin-down for a specific output voltage and margin percentage can then be figured out. Please consult your local Delta Field Application Engineer or sales persons for additional information.

Test

1)Put the resistor with desire of the voltage trim.

2)Turn on the fan.

3)Adjust the input voltage while monitoring DVM2 and with output load set to the desired operating point.

4)Set the enable switch SW2 to the “ON” position to enable converter.

5)Use SW3 (refer to Item 7.1_6) for Trim setup.

6)Note the voltage by observing DVM3.

7)Test the Load Regulation (refer to Item 8.2.2).
