L5972D013TR Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
  • To ensure reliable operation in high-temperature environments, it is recommended to derate the output current and voltage according to the thermal derating curve provided in the datasheet, and to ensure good airflow around the device.
  • STMicroelectronics recommends using X7R or X5R ceramic capacitors with a voltage rating of at least 10V for the input and output capacitors, with a capacitance value of 10uF to 22uF for the input capacitor and 10uF to 47uF for the output capacitor.
  • To protect the device from overvoltage and undervoltage conditions, it is recommended to use a voltage supervisor or a voltage monitor IC to detect and respond to voltage faults, and to add overvoltage protection (OVP) and undervoltage protection (UVP) circuits to the design.
  • The recommended startup sequence for the L5972D013TR is to first apply the input voltage, then enable the device by setting the EN pin high, and finally apply the output load.
