MAX1772EEI+ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MAX1772EEI+ can handle?
  The MAX1772EEI+ can handle input voltages up to 40V, but it's recommended to operate within the 6V to 36V range for optimal performance.
• How do I ensure the MAX1772EEI+ is in a low-power state when not in use?
  To put the MAX1772EEI+ in a low-power state, pull the EN pin low. This will reduce the quiescent current to less than 1µA.
• What is the purpose of the PG pin, and how do I use it?
  The PG pin is a power-good output that indicates when the output voltage is within regulation. You can use it to monitor the output voltage and take action if it falls out of regulation.
• Can I use the MAX1772EEI+ in a high-temperature environment?
  The MAX1772EEI+ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the MAX1772EEI+?
  The output voltage of the MAX1772EEI+ is set by the resistive divider network connected to the FB pin. Use the formula VOUT = 0.8V x (R1 + R2) / R2 to calculate the output voltage.
