PSK-20B-S12 Frequently Asked Questions (FAQ)
-
CUI Inc recommends a PCB layout with a solid ground plane, minimal trace lengths, and a decoupling capacitor (e.g., 10uF) between the input and output pins to reduce noise and ensure stable operation.
-
To ensure reliable startup and shutdown, CUI Inc recommends applying a soft-start circuit or a ramp-up/ramp-down voltage to the input voltage, and using a capacitor (e.g., 10uF) to filter the output voltage.
-
The maximum allowable capacitance on the output is 47uF. Exceeding this value may cause instability or oscillation in the converter.
-
The PSK-20B-S12 is rated for operation up to 85°C ambient temperature. However, derating may be necessary for temperatures above 70°C. Consult the datasheet and CUI Inc's application notes for more information.
-
To troubleshoot output voltage issues, check the input voltage, output load, and PCB layout. Verify that the input voltage is within the specified range, the output load is within the recommended range, and the PCB layout follows CUI Inc's recommendations. Use an oscilloscope to measure the output voltage and check for noise or oscillations.
