MAX267BENG+ datasheet by Maxim Integrated Products

MAX267BENG+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the MAX267BENG+?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the device, and use short, wide traces for the input and output lines.
• How do I ensure the MAX267BENG+ is stable and doesn't oscillate?
  Ensure that the input and output capacitors meet the recommended values and are of high quality. Also, keep the device's output impedance low by using a low-ESR output capacitor and a short, wide trace to the load.
• What is the maximum input voltage that the MAX267BENG+ can handle?
  The MAX267BENG+ can handle input voltages up to 36V, but it's recommended to keep the input voltage below 30V to ensure reliable operation and to prevent damage to the device.
• Can I use the MAX267BENG+ in a high-temperature environment?
  The MAX267BENG+ is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure that the device is properly heatsinked and that the ambient temperature is kept below 85°C for reliable operation.
• How do I calculate the output voltage of the MAX267BENG+?
  The output voltage of the MAX267BENG+ is determined by the resistive divider network connected to the FB pin. Use the formula: VOUT = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
