PT5400 Series
Adjusting the Output Voltage of the PT5400
Series of 6-A SWIFT ? Power Modules
The output voltage of the PT5400 series of SWIFT power
modules may be adjusted higher or lower than the factory
trimmed pre-set voltage with the addition of a single
external resistor. Table 4-1 gives the allowable adjustment
range for each model of the series as V a (min) and V a (max).
The values of (R 1 ) [adjust down], and R 2 [adjust up],
can either be calculated using the following formulas, or
may be looked up from the range of values in Table 4-2.
Refer to Figure 4-1 for the placement of the required
resistor; either (R 1 ) or R 2 as appropriate.
Adjust Up: An increase in the output voltage is obtained by
adding a resistor R 2 , between pin 5 (V o adj) and pin 3 (GND).

the stability of the ISR.
3. For each model, adjustments to the output voltage may
place additional limits on the minimum input voltage. The
revised minimum input voltage must comply with the
following requirement.
V in (min) = (V a + 1.1) V or as specified in the data sheet,
whichever is greater.
4. The PT5408 operates only from a 3.3-V input bus.
The limited input to output voltage differential of this
model does not allow it to be adjusted higher than its
trimmed output voltage.
