MIC4690YM Frequently Asked Questions (FAQs)

  • The MIC4690YM can handle input voltages up to 28V, but it's recommended to operate within the 4.5V to 18V range for optimal performance.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins.
  • The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stable operation.
  • The MIC4690YM is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliability.
  • The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
