LP38693MPX-3.3/NOPB Frequently Asked Questions (FAQ)

  • A good PCB layout for the LP38693MPX-3.3/NOPB involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a separate analog ground plane and to keep the power traces away from the analog signals.

  • To ensure stability, make sure to follow the recommended capacitor values and types, and keep the output capacitor's ESR (Equivalent Series Resistance) within the recommended range. Also, ensure that the input voltage is within the recommended range, and that the device is not operated in a noisy environment.

  • The LP38693MPX-3.3/NOPB can handle input voltages up to 15V, but it's recommended to operate within the recommended input voltage range of 3.5V to 12V for optimal performance and reliability.

  • The LP38693MPX-3.3/NOPB is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the device's performance and consider using thermal management techniques to keep the device within its recommended operating temperature range.

  • To troubleshoot issues, start by verifying the input voltage and current, and checking for any signs of overheating. Then, check the output voltage and current, and verify that the device is not oscillating. If the issue persists, consult the datasheet and application notes, and consider seeking support from Texas Instruments or a qualified engineer.
