Part Number: PTN78020H
I have built a converter based on PTN78020H module . My input voltage range goes from 20V to 26V. The output voltage is set to 17V. I have built the converter using a single side solder breadboard. I have test the converter with a device which requires a current between 1.1A and 1.4A. The output voltage is stable buyt with 20 minutes of activity, the temperature of the custom inductor inside the module goes to 60°C (at the moment I am not using any fan).
Is it a normal behaviour since the module is rated up to 4A? If the module goes in thermal shut-down, could the output become a short-circuit?
I attach the module schematics (I have used 5 4.7uF 50V ceramic capacitor at the input and a 330uF electrolytic capacitor at the output)
