MAX4382EUD+ datasheet by Maxim Integrated Products

MAX4382EUD+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX4382EUD+?
  The recommended PCB layout for the MAX4382EUD+ is to keep the input and output traces as short as possible, and to use a solid ground plane to reduce noise and EMI. Additionally, it's recommended to place a 0.1uF bypass capacitor between the VCC pin and GND pin, and to use a 1uF capacitor between the VIN pin and GND pin.
• How do I ensure the MAX4382EUD+ is stable and doesn't oscillate?
  To ensure the MAX4382EUD+ is stable and doesn't oscillate, make sure to follow the recommended PCB layout, use a sufficient output capacitor (at least 1uF), and ensure that the input voltage is within the recommended range. Additionally, it's recommended to add a 10nF capacitor between the COMP pin and GND pin to improve stability.
• What is the maximum input voltage that the MAX4382EUD+ can handle?
  The maximum input voltage that the MAX4382EUD+ can handle is 28V. However, it's recommended to operate the device within the recommended input voltage range of 4.5V to 24V to ensure reliable operation and to prevent damage to the device.
• Can I use the MAX4382EUD+ in a high-temperature environment?
  The MAX4382EUD+ is rated for operation up to 125°C. However, it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation. Consult the datasheet for more information on thermal derating.
• How do I calculate the output voltage of the MAX4382EUD+?
  The output voltage of the MAX4382EUD+ can be calculated using the following formula: VOUT = (R1/R2) * (VIN - VREF), where R1 and R2 are the resistors connected to the FB pin, VIN is the input voltage, and VREF is the internal reference voltage (1.25V).
