MAX17502HAUD+ datasheet by Maxim Integrated Products

MAX17502HAUD+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX17502HAUD+ to ensure optimal performance?
  A good PCB layout for the MAX17502HAUD+ involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I ensure the MAX17502HAUD+ operates within its safe operating area (SOA) to prevent overheating?
  To ensure the MAX17502HAUD+ operates within its SOA, monitor the input voltage, output current, and ambient temperature. Ensure the device is properly heatsinked, and the thermal resistance (RθJA) is minimized. Use the thermal derating curves in the datasheet to determine the maximum allowable power dissipation.
• What is the recommended input capacitor type and value for the MAX17502HAUD+?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be placed close to the VIN pin and have a voltage rating of at least 2x the maximum input voltage.
• How do I adjust the output voltage of the MAX17502HAUD+?
  The output voltage of the MAX17502HAUD+ can be adjusted by using a resistor divider network between the FB pin and the output voltage. The resistor values can be calculated using the formulae provided in the datasheet.
• What is the purpose of the EN pin on the MAX17502HAUD+, and how do I use it?
  The EN pin is an active-high enable input that allows the user to turn the device on or off. When the EN pin is high, the device is enabled, and when it is low, the device is disabled. The EN pin can be connected to a logic signal or a switch to control the device's operation.
