A6985FTR Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN4979, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The inductor selection depends on the specific application requirements, such as output voltage, current, and switching frequency. STMicroelectronics provides an inductor selection guide in the application note AN4979, which includes a list of recommended inductors and their corresponding characteristics.
  • The maximum junction temperature (Tj) for the A6985FTR is 150°C, as specified in the datasheet. However, it's recommended to keep the junction temperature below 125°C for reliable long-term operation.
  • The A6985FTR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and a capacitor. The application note AN4979 provides a detailed example of how to implement overcurrent protection and calculate the required resistor and capacitor values.
  • STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The application note AN4979 provides more information on input capacitor selection and placement.
