LM2575S-ADJ/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2575S-ADJ/NOPB is 40V, but it's recommended to keep it below 37V for reliable operation.
-
The LM2575S-ADJ/NOPB has a maximum operating junction temperature of 125°C, but it's recommended to keep it below 85°C for reliable operation. You can use thermal management techniques like heat sinks or thermal interfaces to reduce the temperature.
-
The output capacitor should have a minimum value of 22uF and an ESR (Equivalent Series Resistance) of less than 1 ohm. You can use a ceramic or electrolytic capacitor with a voltage rating of at least 1.5 times the output voltage.
-
Yes, the LM2575S-ADJ/NOPB is a switching regulator, but it's not suitable for high-frequency switching power supply designs. It's designed for low-frequency switching applications up to 52 kHz.
-
You can adjust the output voltage by connecting a resistive divider network between the output and the ADJ pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage of 1.23V.
