LM2738XMY/NOPB datasheet by Texas Instruments

LM2738XMY/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LM2738XMY/NOPB to ensure optimal performance?
  A good PCB layout for the LM2738XMY/NOPB involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces to reduce EMI and noise.
• How do I ensure the LM2738XMY/NOPB is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended component values and PCB layout, and add a small capacitor (e.g., 10nF) between the Vout and Vin pins to prevent oscillation.
• What is the maximum input voltage that the LM2738XMY/NOPB can handle?
  The LM2738XMY/NOPB can handle input voltages up to 42V, but it's recommended to keep the input voltage below 40V to ensure reliable operation.
• Can I use the LM2738XMY/NOPB in a high-temperature environment?
  The LM2738XMY/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LM2738XMY/NOPB?
  The output voltage of the LM2738XMY/NOPB can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the internal reference voltage (1.25V).
