BA17809FP-E2 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 minimum of 2oz copper thickness is recommended.
  • To ensure stable operation with a high-ESR capacitor, add a 1-10nF ceramic capacitor in parallel with the output capacitor to reduce the overall ESR and improve stability.
  • The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the device. It's recommended to use a voltage divider or a clamp circuit to limit the voltage to 6V or less.
  • While the BA17809FP-E2 is rated for operation up to 105°C, it's essential to consider the derating of the output current and power dissipation at higher temperatures to ensure reliable operation.
  • To troubleshoot oscillations or instability issues, check the PCB layout for noise coupling, ensure proper decoupling capacitors are used, and verify that the output capacitor meets the recommended specifications.
