LM26400YMH/NOPB datasheet by Texas Instruments

LM26400YMH/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the LM26400YMH/NOPB?
  A good PCB layout for the LM26400YMH/NOPB involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I ensure the stability of the LM26400YMH/NOPB in my design?
  To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Also, ensure that the input voltage is within the recommended range, and the output capacitor is of sufficient value and type (e.g., X5R or X7R). Additionally, avoid using long traces and minimize the inductance in the output stage.
• What is the maximum ambient temperature range for the LM26400YMH/NOPB?
  The LM26400YMH/NOPB is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range may be limited by the specific application and the thermal design of the system.
• Can I use the LM26400YMH/NOPB in a high-reliability or automotive application?
  Yes, the LM26400YMH/NOPB is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard and is suitable for use in harsh environments.
• How do I troubleshoot issues with the LM26400YMH/NOPB in my design?
  To troubleshoot issues, start by verifying the input voltage and current, and checking for any signs of overheating. Use an oscilloscope to check the output voltage and current waveforms. Also, ensure that the PCB layout and component values are correct, and that the device is properly soldered and connected.
