BU7485G-TR Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A 4-layer PCB with a thermal via is also recommended.
  • ROHM recommends a soft-start circuit to limit inrush current during power-up, and a power-down sequence that ensures the output voltage is fully discharged before turning off the input voltage.
  • The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the internal circuitry. A voltage limiter or a resistor divider network can be used to ensure the voltage stays within the recommended range.
  • While the BU7485G-TR is rated for operation up to 125°C, ROHM recommends derating the output current and voltage to ensure reliable operation in high-temperature environments. Consult the datasheet for derating curves and guidelines.
  • ROHM recommends checking the PCB layout for noise coupling, ensuring proper decoupling capacitors are used, and verifying the input voltage and output load conditions are within the recommended specifications. A scope probe can be used to measure the output voltage and identify any oscillations or ringing.
