SB140 Frequently Asked Questions (FAQs)

  • A good PCB layout for the SB140 involves keeping the input and output traces separate, using a solid ground plane, and placing the input and output capacitors close to the device. Additionally, it's recommended to use a shielded inductor and to keep the switching node (pin 5) away from sensitive nodes.
  • To ensure stability, make sure the output capacitor is properly sized and placed close to the device. Also, ensure the input voltage is within the recommended range, and the output load is within the specified range. Additionally, a small capacitor (e.g., 10nF) can be added between the output and ground to improve stability.
  • The SB140 can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The output voltage of the SB140 can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the feedback resistors, Vin is the input voltage, and Vref is the internal reference voltage (typically 2.5V).
  • The SB140 can deliver up to 2A of output current, but it's recommended to keep the output current below 1.5A to ensure reliable operation and to prevent overheating.
