MAX1640EEE+ datasheet by Maxim Integrated Products

MAX1640EEE+ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MAX1640EEE+ can handle?
  The MAX1640EEE+ can handle input voltages up to 40V, but it's recommended to operate within the specified input voltage range of 4.5V to 40V for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the purpose of the EN (enable) pin, and how do I use it?
  The EN pin is used to enable or disable the regulator. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled. Connect EN to VIN if you want the regulator to be always-on.
• How do I calculate the output voltage of the MAX1640EEE+?
  The output voltage can be calculated using the formula: VOUT = (R1 / R2) x 1.25V, where R1 and R2 are the resistors connected to the FB (feedback) pin.
• What is the maximum current that the MAX1640EEE+ can deliver?
  The MAX1640EEE+ can deliver up to 1.5A of output current, but it's recommended to operate within the specified current range for optimal performance and to prevent overheating.
