(ISRs). Designed for general purpose industrial applications requiring as much as 5A of output current, the PT6650 is packaged in a 14-Pin SIP (Single In-line Package) and is available in a surface-mount configuration. Only two external capacitors are required for proper operation. Please note that this product does not include short circuit protection.

T able 1 accordingly gives the allowable adjustment range for each model in the 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 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 able 2 for both the placement and value of the required resistor, either (R1) or R2 as appropriate. Notes: 1. Use only a single 1% resistorin either the (R1) or R2 loca- tion. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from V o 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 + 3, or 9V , whichever is higher. 5. For output voltages above 12.5Vdc, the maximum output current must be limited to 4Adc. The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulae. Ro (Vo – 1.25)(Va – 1.25)(R1) = 1.25 (Vo – Va) – Rs kΩ Ro (Vo – 1.25) – Rs kΩR2 = Va - Vo Where: V o = Original output voltage Va = Adjusted output voltage Ro = The resistance value in T able 1 Rs = The series resistance from T able 1 Figure 1 Table 1 PT6650 ADJUSTMENT AND FORMULA PARAMETERS Series Pt # PT6652 PT6651 PT6653 PT6654 PT6656 PT6655 C in 100 µ F + C out 330 µ F (R1) Adj Down Adjust Up Vo COMCOM Vin L O A D PT6650 11,12,13 147,8,9,10 4,5,6 Vin Vo GND Vo(adj)STBY Vsense
