The PT6300 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications. The ISR will operate to no load with reduced specifications. Input voltage cannot exceed 30V when the inhibit function is used. See Thermal Derating charts. Consult the related application note for guidance on adjusting the output voltage.

Application Notes
PT6100/6210/6300 Series
Adjusting the Output Voltage of Power Trends' Wide Input Range Bus ISRs
The output voltage of the Power Trends' Wide Input Range 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 for either series as Va (min) and Va (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor R2, between pin 12 (Vo adjust) and pins 5-8 (GND). Adjust Down: Add a resistor (R1), between pin 12 (Vo adjust) and pins 9-11(Vout).
Figure 1
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 Vo adjust to either GND or Vout. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3 . Adjustments to the output voltage may place additional limits on the maximum and minimum input voltage for the part. The revised maximum and minimum input voltage limits must comply with the following requirements. The limits are model dependant.
PT6216/PT6314:
Vin (max) = (10 x Va)V or 17V, whichever is less. Vin (min) = 9.0V

The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas. Refer to Figure 1 and Table 2 for both the placement and value of the required resistor; either (R1) or R2 as appropriate. Ro (Va 1.25) Vo Va 1.25 Ro Va Vo
