ADM7155ARDZ-02-R7 Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADM7155ARDZ-02-R7 involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a separate analog ground plane and to keep the device away from high-frequency noise sources.
  • To ensure proper power-up and initialization, make sure to follow the recommended power-up sequence, which is to apply the input voltage (VIN) before the enable pin (EN). Also, ensure that the input voltage is within the recommended range and that the enable pin is properly biased.
  • The maximum output current of the ADM7155ARDZ-02-R7 is 1.5A. However, it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
  • The ADM7155ARDZ-02-R7 has built-in OVP and UVLO features. For OVP, the device will automatically shut down if the input voltage exceeds 6.5V. For UVLO, the device will not turn on until the input voltage reaches 2.2V. You can also use external resistors to adjust the UVLO threshold if needed.
  • The recommended input capacitor value is 1uF to 10uF, and it's recommended to use a low-ESR ceramic capacitor (X5R or X7R dielectric) to minimize input voltage ripple and ensure stable operation.
