T able 1 accordingly gives the allowable adjustment range for each model for either series as V a (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 The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas. Refer to Figure 1 and T able 2 for both the placement and value of the required resistor; either (R1) or R2 as appropriate. Ro (Va – 1.25)(R1) = Vo – Va kΩ

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 All other models: Vin (max) = (8 x Va)V or as specified. Vin (min) = (Va + 4)V or 9V , whichever is greater.
