LM2675N-5.0 datasheet by Texas Instruments

LM2675N-5.0 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2675N-5.0?
  The maximum input voltage that can be applied to the LM2675N-5.0 is 40V, but it's recommended to keep it below 30V for reliable operation.
• Can I use the LM2675N-5.0 in a high-temperature environment?
  The LM2675N-5.0 has a maximum operating junction temperature of 150°C, but it's recommended to keep it below 125°C for reliable operation. You can use thermal management techniques like heat sinks or thermal interfaces to reduce the junction temperature.
• How do I ensure the output voltage is accurate and stable?
  To ensure the output voltage is accurate and stable, make sure to use a stable input voltage, use a high-quality output capacitor with low ESR, and keep the feedback resistors (R1 and R2) within the recommended range (1kΩ to 10kΩ).
• What is the minimum input capacitance required for the LM2675N-5.0?
  The minimum input capacitance required for the LM2675N-5.0 is 10uF, but it's recommended to use a higher value (22uF or more) to ensure stable operation and reduce input voltage ripple.
• Can I use the LM2675N-5.0 in a switching noise-sensitive application?
  The LM2675N-5.0 has a switching frequency of around 260kHz, which can generate noise. To minimize noise, use a shielded inductor, keep the layout compact, and use noise-reducing components like ferrite beads or common-mode chokes.
