AON7405 datasheet by Alpha & Omega Semiconductor

AON7405 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the AON7405?
  The AON7405 can operate from -40°C to 150°C, making it suitable for high-reliability applications.
• How do I ensure the AON7405 is properly biased for optimal performance?
  To ensure proper biasing, connect the EN pin to VIN, and the FB pin to a resistive divider network that sets the output voltage. Also, ensure the input capacitor is properly sized to handle the input ripple current.
• What is the recommended input capacitor type and value for the AON7405?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. This helps to reduce input ripple voltage and ensure stable operation.
• How do I calculate the output voltage of the AON7405?
  The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the feedback network.
• What is the maximum output current capability of the AON7405?
  The AON7405 can deliver up to 5A of output current, making it suitable for high-current applications.
