PT6500/PT6600 Series

Adjusting the Output Voltage of the PT6500 and
PT6600 5V Bus Converters

The output voltage of the Power Trends PT6500/PT6600
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 (V

o

adjust) and pins 7-10

(GND).

Adjust Down: Add a resistor (R1), between pin 14 (V

o

adjust)

and pins 11-13 (V

out

).

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% resistor in either the (R1) or R2 loca­tion. Place the resistor as close to the ISR as possible.

2. Never connect capacitors from V

o

adjust to either GND,

V

out

, 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
V

out

+ 1.2 or 3.1V, whichever is higher.
