Application Notes

PT6460 & PT6470 Series

Adjusting the Output Voltage of the PT6460 &

PT6470 ISR Series

The output voltage of the PT6460 (5-V input) and the

PT6470 (3.3-V input) series of power modules may be

adjusted higher or lower than the pre-set voltage. The

adjustment method requires a single external resistor.

The value of the resistor can either be calculated using

the formulas given below, or simply selected from the

range of values given in Table 3-2. Table 3-1 gives the

allowable adjustment range for each model as V_a(min)

and V_a(max). Refer to Figure 3-1 for the placement of

the required resistor. Resistor R₁adjusts the output voltage

up, and the resistor (R₂) adjusts it down.

The values of (R₁) [adjust down], and R₂[adjust up],

can be calculated using the following formulas. Refer to

Figure 3-1 for the placement of the required resistor;

either (R₁) or R₂as appropriate.

R₂

Where:

= Original output voltage

= Adjusted output voltage

Adjust Up: An increase in the output voltage is obtained

by adding a resistor R₂, between V_oAdjust (pin 12) and

GND (pin 5).

R_o= The resistance value from Table 3-1

R_s= The series resistance from Table 3-1

Notes:

Adjust Down: Add a resistor (R₁), between V_oAdjust (pin 12)

and +Vsense (pin 11).

1. Use a 1 % (or better) tolerance resistor in either the (R₁)

or R₂location. Place the resistor as close to the ISR as

possible.

Figure 3-1

2. Never connect capacitors from V_oadj to either GND or

V_out. Any capacitance added to the V_oadjust pin will affect

the stability of the ISR.

4. The PT6472 may not be adjusted higher than the

nominal output voltage of 2.5 V. There is insuf ficient

input voltage to allow for any increase in output voltage.
