PT6650 Series
Adjusting the Output Voltage of the
PT6650 5Amp 24V Bus Converter Series
The output voltage of the Power Trends PT6650 Series ISRs
may be adjusted higher or lower than the factory trimmed pre-
set voltage with the addition of a single external resistor. Table 1
accordingly gives the allowable adjustment range for each model
in the series as Va (min) and Va (max).
Adjust Up:
An increase in the output voltage is obtained by
adding a resistor R2, between pin 14 (Vo adjust) and pins 7-10
(GND).
Adjust Down:
Add a resistor (R1), between pin 14 (Vo adjust)
and pins 11-13 (Vout).
Refer to Figure 1 and Table 2 for both the placement and value
of the required resistor, either (R1) or R2 as appropriate.
Notes:
1. Use only a single 1% resistorin either the (R1) or R2 loca-
tion. Place the resistor as close to the ISR as possible.
2. Never connect capacitors from Vo adjust to either GND,
Vout, or the Remote Sense pin. Any capacitance added to
the Vo adjust pin will affect the stability of the ISR.
3. If the Remote Sense feature is being used, connecting the
resistor (R1) between pin 14 (Vo adjust) and pin 1 (Remote
Sense) can benefit load regulation.
4. The minimum input voltage required by the part is Vout + 3,
or 9V, whichever is higher.
5. For output voltages above 12.5Vdc, the maximum output
current must be limited to 4Adc.
The values of (R1) [adjust down], and R2 [adjust up], can
also be calculated using the following formulae.
Ro (Vo – 1.25)(Va – 1.25)
(R1)

1.25 (Vo – Va)

Va = Adjusted output voltage
Ro = The resistance value in Table 1
Rs = The series resistance from Table 1
