MAX1873REEE+ datasheet by Maxim Integrated Products

MAX1873REEE+ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MAX1873REEE+ can handle?
  The MAX1873REEE+ can handle input voltages up to 32V, but it's recommended to operate within the 7V to 28V range 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 maximum output current that the MAX1873REEE+ can provide?
  The MAX1873REEE+ can provide up to 3A of output current, but it's recommended to operate within the 1A to 2A range for optimal performance and thermal management.
• How do I adjust the output voltage of the MAX1873REEE+?
  The output voltage can be adjusted by using a resistive divider network between the output pin and the feedback pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula provided in the datasheet.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator during shutdown or standby modes.
