LTC491CS#TRPBF Frequently Asked Questions (FAQ)

  • A good PCB layout for the LTC491CS#TRPBF involves keeping the input and output traces short and separate, using a solid ground plane, and placing the input and output capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.

  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor is properly sized and placed, and that the input voltage is within the recommended range. If oscillations occur, try adding a small capacitor (e.g. 10nF) between the VCC pin and ground.

  • The LTC491CS#TRPBF is rated for operation up to 125°C ambient temperature, but it's recommended to derate the device for reliable operation above 85°C. Consult the datasheet for thermal derating guidelines.

  • While it's possible to use a different inductor value or type, it's not recommended as it may affect the device's performance and stability. The recommended inductor value and type are carefully selected to ensure optimal performance and efficiency. If you must use a different inductor, consult with Linear Technology's application engineers for guidance.

  • To troubleshoot issues, start by checking the input voltage, output voltage, and current. Verify that the component values and PCB layout match the recommended design. Check for signs of overheating, and ensure that the device is properly soldered and connected. Consult the datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
