The PT6650 series is line of 24V bus Integrated Switching Regulators (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.

Notes: (1) (2) (3) (4)
The PT6650 Series requires a 330µF electrolytic capacitor at the output, and a 560µF at the input for proper operation in all applications. The input capacitor must be have a low ESR, and be rated for 1.4Arms of ripple current. ISR will operate down to no load with reduced specifications. See SOA curves, or contact the factory for the appropriate derating.

Application Notes
PT6650 Series
Adjusting the Output Voltage of the PT6650 5Amp 24V Bus Converter Series
The output voltage of the Power Trends PT6650 Series ISRs may be adjusted higher or lower than the factory trimmed pre-set voltage with the addition of a single external resistor. T ble 1 accordingly gives the allowable a 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. Adjustments to the output voltage may place additional limits on the input voltage for the part. The revised limits must comply with the following requirements. = (Vout + 3)V or 9V, Vin (min) whichever is higher. = (10 x Vout )V or 28V, Vin (max) whichever is less. 5. For output voltages above 12.5Vdc, the maximum output current must be limited to 4Adc.
