BA178M18FP-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.
  • Ensure proper heat sinking, avoid exceeding the maximum junction temperature (Tj) of 150°C, and consider derating the device's power dissipation according to the ambient temperature.
  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling, placed as close to the device as possible.
  • Yes, the BA178M18FP-E2 is suitable for switching regulator applications. However, ensure that the device is properly bypassed and the output is filtered to minimize noise and ripple.
  • Use a voltage supervisor or overvoltage protection (OVP) circuit to prevent voltage exceeding the maximum rating. Also, consider adding overcurrent protection (OCP) using a sense resistor and a comparator or a dedicated OCP IC.
