    MAX791CSE+ Frequently Asked Questions (FAQs)

    • The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input voltage ripple and improve output voltage regulation.
    • To ensure the MAX791CSE+ operates within its SOA, ensure that the input voltage, output current, and ambient temperature are within the recommended operating ranges specified in the datasheet. Additionally, ensure that the device is properly heat-sinked and that the thermal resistance (RθJA) is within the recommended range.
    • The maximum output current capability of the MAX791CSE+ is 1A. However, the actual output current capability may be limited by the input voltage, output voltage, and ambient temperature. Refer to the datasheet for more information on output current capability vs. input voltage and temperature.
    • The MAX791CSE+ has a built-in overcurrent protection feature that limits the output current to a maximum of 1.5A. To implement overcurrent protection, connect a sense resistor (Rs) between the output pin and the GND pin. The value of Rs determines the overcurrent threshold. Refer to the datasheet for more information on implementing overcurrent protection.
    • The EN (enable) pin is used to enable or disable the MAX791CSE+. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and the output voltage is turned off. The EN pin can be used to implement power sequencing or to turn off the device during shutdown or standby modes.
