DRC2143T0L datasheet by Panasonic Electronic Components

DRC2143T0L Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the DRC2143T0L?
  Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the DC-DC converter. The input and output capacitors should be placed close to the IC, and the feedback resistors should be placed near the output capacitor.
• How do I ensure the stability of the output voltage in the DRC2143T0L?
  To ensure stability, the output capacitor should be a low-ESR type with a value between 10uF to 22uF. The output voltage can be further stabilized by adding a 1uF to 10uF ceramic capacitor in parallel with the output capacitor.
• What is the maximum ambient temperature for the DRC2143T0L?
  The maximum ambient temperature for the DRC2143T0L is 85°C, but it can be derated to 70°C for high-reliability applications.
• Can I use the DRC2143T0L in a high-vibration environment?
  Yes, the DRC2143T0L is designed to withstand vibrations up to 10G (10Hz to 2kHz) and can be used in high-vibration environments such as automotive or industrial applications.
• How do I handle the thermal shutdown feature of the DRC2143T0L?
  The thermal shutdown feature is activated when the junction temperature exceeds 150°C. To handle this, ensure good thermal design and heat dissipation, and consider adding a thermal monitoring circuit to detect and respond to thermal shutdown events.
