MAX8546EUB+ datasheet by Maxim Integrated Products

MAX8546EUB+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX8546EUB+?
  The recommended PCB layout for the MAX8546EUB+ is to keep the input and output capacitors close to the device, and to use a solid ground plane to reduce noise and improve stability. Additionally, it is recommended to use a separate power plane for the input voltage and to keep the output voltage traces away from the input voltage traces.
• How do I ensure the MAX8546EUB+ is stable and does not oscillate?
  To ensure the MAX8546EUB+ is stable and does not oscillate, it is recommended to follow the recommended PCB layout, use a sufficient output capacitor (at least 10uF), and to ensure that the input voltage is within the recommended range. Additionally, it is recommended to add a small ceramic capacitor (around 10nF) between the output and ground to improve stability.
• What is the maximum input voltage that can be applied to the MAX8546EUB+?
  The maximum input voltage that can be applied to the MAX8546EUB+ is 6.5V. Exceeding this voltage may damage the device.
• Can the MAX8546EUB+ be used in a high-temperature environment?
  The MAX8546EUB+ is rated for operation up to 125°C. However, it is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the MAX8546EUB+?
  The output voltage of the MAX8546EUB+ can be calculated using the following formula: VOUT = (VIN x (R1/R2)) + VREF, where VIN is the input voltage, R1 and R2 are the feedback resistors, and VREF is the internal reference voltage (1.25V).
