PM6670ASTR Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN4571, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
  • The input capacitor values depend on the input voltage, output voltage, and output current. A general guideline is to use a minimum of 10uF ceramic capacitors with a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN4571 for more detailed guidance.
  • The maximum allowed voltage on the EN (enable) pin is 6V. Exceeding this voltage may damage the device. It's recommended to use a voltage divider or a level shifter if the control signal is higher than 6V.
  • The PM6670ASTR is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures. It's essential to follow the recommended thermal design guidelines and consider derating the device's performance at high temperatures.
  • To ensure EMC, follow the guidelines in the application note AN4571, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and a filter capacitor to reduce electromagnetic interference (EMI).
