PT5060 Series
Adjusting the Output Voltage of the PT5060
Dual-Output Boost Converter Series
The dual output voltage of the PT5060 series modules
can be adjusted higher or lower than the factory pre-set
voltage with the addition of a single external resistor.
Table 1 gives the applicable 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 11 (Vo adj) and pins
2, 6, or 7 (GND).
Adjust Down:
Add a resistor (R1), between pin 11 (Vo adj)
and pins 8, 9 or 10 (Vo1).
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. Both the positive and negative voltage outputs from the
ISR are adjusted simultaneously.
2. Use only a single 1% resistor in either the (R1) or R2
location. Place the resistor as close to the ISR as possible.
3. Never connect capacitors from Vo adj to either GND or
Vo. Any capacitance added to the Vo adjust pin will affect
the stability of the ISR.
4. An increase in the output voltage must be accompanied by
a corresponding reduction in the specified maximum
current at each output. For Vo1 and –Vo2, the revised
maximum output current must be reduced to the
equivalent of 6 watts and 3 watts respectively. i.e.
Io1 (max)
=
6
Adc
Va
and
Io2 (max)
=
3
Adc,
Va
where Va is the adjusted output voltage.
5. Adjustments to the output voltage will also limit the
maximum input voltage that can be applied to the ISR.
The maximum input voltage that may be applied is limited
to (Vo – 1)Vdc or 14Vdc, whichever is less.
