Notes: (1) The PT6600 series requires two 330µF electrolytic capacitors (input and output) for proper operation in all applications. The input capacitance must be rated for a minimum of 1.1Arms of ripple current. See the application note, PT6500/6600 Series Capacitor Recommendations. (2) ISR will operate down to no load with reduced specifications. (3) For operation below 0°C, use tantalum capacitors for CIN and COUT. For more information, contact an Application Specialist. (4) See Safe Operating Curves, or contact the factory for the appropriate derating.

Application Notes
PT6600 Series
Adjusting the Output Voltage of the PT6 6 0 0 5V Bus Converters
The output voltage of the Power Trends PT6600 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 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 14 (Vo adjust) and pins 7-10 (GND).

Adjust Down: Add a resistor (R1), between pin 14 (Vo adjust) and pins 11-13 (Vout). Refer to Figure 1 and T ble 2 for both the placement and value a of the required resistor, either (R1) or R2 as appropriate. 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, Vout, or the Remote Sense pin. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3. If the Remote Sense feature is being used, connecting the resistor (R1) between pin 14 (Vo adjust) and pin 1 (Remote Sense) can benefit load regulation. 4. The minimum input voltage required by the part is Vout + 1.2 or 3.1V, whichever is higher.
The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulae. Ro (Va ­ 1.0) (Vo ­ Va)
