TL28L92FR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise and coupling.
  • Ensure the output capacitor is properly sized and placed close to the output pin. Also, add a 10nF-100nF capacitor between the VIN and GND pins to filter out noise.
  • Although the datasheet specifies a maximum input voltage of 28V, it's recommended to limit the input voltage to 24V to ensure reliable operation and prevent overheating.
  • The TL28L92FR is rated for operation up to 125°C, but it's essential to ensure proper heat sinking and thermal management to prevent overheating and reduce the risk of thermal shutdown.
  • The output capacitor value depends on the output voltage and current requirements. A general rule of thumb is to use a capacitor with a value between 10uF to 100uF, with a voltage rating of at least 2x the output voltage.
