MAX4664CSE+T datasheet by Maxim Integrated Products

MAX4664CSE+T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX4664CSE+T to ensure optimal performance?
  The recommended PCB layout for the MAX4664CSE+T involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the IC and the load. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
• How do I ensure the MAX4664CSE+T is properly powered and decoupled?
  To ensure the MAX4664CSE+T is properly powered and decoupled, use a high-quality power supply with low noise and ripple, and decouple the power pins with 0.1uF and 10uF capacitors. Additionally, use a 1uF capacitor between the VCC and GND pins to filter out high-frequency noise.
• What is the maximum load current that the MAX4664CSE+T can handle?
  The MAX4664CSE+T can handle a maximum load current of 100mA. However, it's recommended to derate the current based on the ambient temperature and the package type. Refer to the datasheet for more information on thermal derating.
• How do I program the MAX4664CSE+T to achieve the desired output voltage?
  The MAX4664CSE+T can be programmed using an external resistor divider network connected to the FB pin. The output voltage can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
• What is the typical startup time for the MAX4664CSE+T?
  The typical startup time for the MAX4664CSE+T is around 100us. However, this time can vary depending on the input voltage, output voltage, and load current. Refer to the datasheet for more information on startup time vs. input voltage.
