BA6845FS Frequently Asked Questions (FAQs)

  • A good PCB layout for the BA6845FS involves keeping the input and output traces short and separate, using a solid ground plane, and placing decoupling capacitors close to the IC. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure the stability of the output voltage, it is essential to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. A 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric is recommended.
  • The BA6845FS can handle a maximum input voltage of 18V. However, it is recommended to operate the IC within the specified input voltage range of 7V to 15V for optimal performance and reliability.
  • To protect the BA6845FS from overcurrent and overheating, it is recommended to add an external current limit resistor and a thermal protection circuit. The IC also has a built-in thermal shutdown feature that turns off the output when the junction temperature exceeds 150°C.
  • The BA6845FS is rated for operation up to 85°C ambient temperature. However, the IC's performance and reliability may degrade at higher temperatures. It is recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet.
