MAX8860EUA18+ datasheet by Maxim Integrated Products

MAX8860EUA18+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX8860EUA18+ to ensure optimal performance?
  A good PCB layout for the MAX8860EUA18+ should include a solid ground plane, separate analog and digital grounds, and a decoupling capacitor (e.g., 1uF) between VCC and GND. Additionally, keep the input and output traces short and away from noise sources.
• How do I ensure the MAX8860EUA18+ is stable and doesn't oscillate?
  To ensure stability, make sure the output capacitor (COUT) is within the recommended range (10uF to 22uF), and the input capacitor (CIN) is at least 1uF. Also, ensure the feedback resistors (RFB1 and RFB2) are within the recommended range (1kΩ to 10kΩ).
• What is the maximum input voltage that the MAX8860EUA18+ can handle?
  The MAX8860EUA18+ 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.
• Can I use the MAX8860EUA18+ in a high-temperature environment?
  The MAX8860EUA18+ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.
• How do I calculate the output voltage of the MAX8860EUA18+?
  The output voltage (VOUT) of the MAX8860EUA18+ can be calculated using the formula: VOUT = (RFB2 / RFB1) * (VREF - VFB), where VREF is the internal reference voltage (1.25V) and VFB is the feedback voltage.
