More Application Notes  
Adjusting the Output Voltage of the PT3320 /  
PT3340 Series of Isolated DC-DC Converters  
3ꢁ If the remote sense pins are not being used, the resistors (R1)  
and R2 can be connected to +Vout or -Vout respectivelyꢁ  
4ꢁ The adjusted output voltage Va effectively sets the voltage  
across pins 13 and 19 ( Remote Sense)ꢁ When using the  
remote sense pins, Vout (measured directly across pins 10–12,  
and 14–17) can be significantly higher than Va, and may  
exceed Vo (max)ꢁ If Va is adjusted upward, the alternative is  
to increase the minimum input voltage by the same percent-  
age as Vout exceeds Vo(max)ꢁ  
The factory pre-set output voltage of Power Trends’ PT3320  
and PT3340 series DC-DC converters may be adjusted within a  
nominal 10ꢀ rangeꢁ This is accomplished with the addition of  
a single external resistorꢁ For the input voltage range specified in  
the data sheet, Table 1 gives the allowable adjustment range for  
each model as Vo (min) and Vo (max)ꢁ  
Adjust Up:  
An increase in the output voltage is obtained by  
adding a resistor, R2 between pin 18 (Vo adjust), and pin 13  
(-Remote Sense)ꢁ See note 4ꢁ  
The values of (R1) [adjust down], and R2 [adjust up], can also be  
calculated using the following formulasꢁ  
Adjust Down: Add a resistor (R1), between pin 18 (Vo adjust)  
and pin 19 (+Remote Sense)ꢁ  
Ro (Vo – Vr)(Va – Vr)  
(R1)  
=
=
– Rs k  
kΩ  
Vr (Vo – Va)  
Refer to Figure 1 and Table 2 for both the placement and value  
of the required resistor, (R1) or R2ꢁ  
Ro (Vo – Vr)  
(Va – Vo)  
R2  
– Rs  
Notes:  
Where  
Vo = Original output voltage  
Va = Adjusted output voltage  
Vr = Reference voltage (Table 1)  
Ro = Multiplier resistance (Table 1)  
Rs = Series resistance (Table 1)  
1ꢁ Use only a single 1ꢀ resistor in either the (R1) or R2 loca-  
tionꢁ Place the resistor as close to the ISR as possibleꢁ  
2ꢁ Never connect capacitors to Vo adjustꢁ Any capacitance  
added to the Vo adjust control pin will affect the stability of  
the ISRꢁ
