Test

1.Put the resistor to program the desired output voltage set point by follow Table 1 and Table 2 for the standard output.

2.Set the input voltage to the desired operating level while monitoring DVM2.

3.Turn on the fan.

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

5.Adjust the output load across the converter’s operating load range.

6.Note the output voltage over the full range of the operating load range (please refer to the data sheet for the detailed specification).

(2)Output Voltage Set-Point Adjustment by external voltage source

For DNM and DNL series, trim to Vo,set using an external voltage source, connect it between the TRIM pin and GND pin. Please refer to the Table 3 and Table 4 as below for the appropriate Vout. The value of Vtrim is specified as follows:

For DNM04xx and DNL04xx series

Vtrim = 0.7 − 0.1698 ⋅ (Vout − 0.7525)

For example, to program the output voltage of a DNL04 module to 3.3 Vdc, Vtrim is

calculated as follows:

 

 

 

Vtrim = 0.7 − 0.1698 ⋅ (3.3 − 0.7525) = 0.267V
