UCD9090ARGZT Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to ensure good heat dissipation.
  • The UCD9090ARGZT requires a specific power-up sequence to ensure proper operation. TI recommends powering up the device in the following order: VIN, VDD, and then VOUT.
  • The maximum capacitance value for the output capacitors is 100uF. Exceeding this value may cause stability issues and affect the device's performance.
  • The output voltage can be adjusted by modifying the resistor divider network connected to the FB pin. TI provides a calculation tool to help determine the required resistor values.
  • TI recommends a 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric for the VIN pin to ensure stable operation.
