PM8803TR Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the device to ensure optimal thermal performance.
  • To ensure reliable operation at high temperatures, it is recommended to derate the output current and voltage according to the thermal derating curve provided in the datasheet, and to ensure good thermal conduction between the device and the heat sink.
  • STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the input voltage and output current requirements, to ensure optimal performance and stability.
  • To troubleshoot issues with the device not turning on or not regulating properly, check the input voltage, output voltage, and enable pin voltage levels, and ensure that the device is properly configured and connected according to the datasheet.
  • STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the output voltage and current requirements, to ensure optimal performance and stability.
