LM2737MTCX/NOPB datasheet by Texas Instruments

LM2737MTCX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2737MTCX/NOPB?
  The maximum input voltage that can be applied to the LM2737MTCX/NOPB is 15V, but it's recommended to operate within the specified input voltage range of 6.5V to 14V for optimal performance and reliability.
• How do I ensure the stability of the output voltage in my design?
  To ensure the stability of the output voltage, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and ensure that the input voltage is within the specified range. Additionally, consider adding a soft-start circuit to prevent inrush currents during startup.
• What is the maximum output current that the LM2737MTCX/NOPB can deliver?
  The LM2737MTCX/NOPB can deliver up to 3A of output current, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
• How do I handle thermal considerations for the LM2737MTCX/NOPB?
  To handle thermal considerations, ensure good airflow around the device, use a heat sink if necessary, and follow the recommended thermal design guidelines. The junction temperature (TJ) should be kept below 125°C to ensure reliable operation.
• What are the EMI considerations for the LM2737MTCX/NOPB?
  To minimize EMI, use a shielded inductor, keep the switching node (SW) away from sensitive analog circuits, and use a common-mode choke or ferrite bead to filter the output. Additionally, follow good PCB layout practices to minimize radiated emissions.
