LM2594M-3.3/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2594M-3.3/NOPB is 40V, but it's recommended to keep it below 35V for reliable operation.

  • The LM2594M-3.3/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.

  • To ensure the stability of the output voltage, make sure to use the recommended output capacitor value and type, and keep the output capacitor close to the IC. Also, ensure that the input voltage is within the recommended range and the input capacitor is properly sized.

  • The LM2594M-3.3/NOPB is a switching regulator, and it can generate switching noise. To minimize the noise, use a proper PCB layout, keep the input and output capacitors close to the IC, and use a shielded inductor. You can also add a noise filter or a ferrite bead to the output to reduce the noise.

  • The output current capability of the LM2594M-3.3/NOPB depends on the input voltage, output voltage, and ambient temperature. You can use the datasheet's thermal derating curves and output current vs. input voltage graphs to estimate the output current capability. As a general rule, the maximum output current is around 3A.
