MP1580HS-LF-Z datasheet by Monolithic Power Systems

MP1580HS-LF-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP1580HS-LF-Z can handle?
  The MP1580HS-LF-Z can handle input voltages up to 60V, but it's recommended to keep it below 50V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output capacitor is placed close to the IC and the feedback pin is connected to the output capacitor.
• What is the maximum output current that the MP1580HS-LF-Z can provide?
  The MP1580HS-LF-Z can provide up to 2A of output current, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
• How do I adjust the output voltage?
  The output voltage can be adjusted by using a resistive divider network between the output and the feedback pin. The ratio of the resistors determines the output voltage, and the recommended ratio is 1:1 for a 5V output.
• 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. Connect the EN pin to VIN to enable the regulator, or connect it to GND to disable it. The EN pin can also be used to implement power sequencing or to turn the regulator on/off dynamically.
