PT6600 Series
Adjusting the Output Voltage of the
PT6600 5V Bus Converters
The output voltage of the Power Trends 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 V
a (min)
and V
a (max).
Adjust Up:
An increase in the output voltage is
obtained by adding a resistor R2, between pin 14 (V
o ad-
just) 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 V
o 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 (V
o
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.
