LM3658SDX-B/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to minimize thermal resistance. Additionally, placing the device near a thermal pad or heat sink can improve thermal performance.
  • To ensure reliable start-up and operation with a low input voltage, it is recommended to add a capacitor (e.g., 10uF) between the VIN pin and GND to filter out noise and voltage droops. Additionally, a soft-start circuit can be implemented to reduce inrush current and prevent voltage drops during start-up.
  • The maximum output current capability of the LM3658SDX-B/NOPB is 3A, but it is recommended to derate the output current based on the ambient temperature and PCB thermal design to ensure reliable operation.
  • To protect the device from overvoltage and undervoltage conditions, it is recommended to add overvoltage protection (OVP) and undervoltage protection (UVP) circuits. For example, a zener diode can be used to clamp the input voltage to a maximum value, and a voltage supervisor IC can be used to detect undervoltage conditions and reset the device.
  • Texas Instruments recommends using a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF between the VIN pin and GND to filter out noise and voltage droops. The capacitor value should be selected based on the input voltage ripple and noise requirements.
