LT3990HMSE#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT3990 involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance. 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 has a low ESR (Equivalent Series Resistance) and is properly decoupled from the input capacitor. A minimum output capacitance of 10uF is recommended.
  • The LT3990 can handle input voltages up to 60V, but it's recommended to operate within the specified input voltage range of 7V to 40V for optimal performance and reliability.
  • The LT3990 is rated for operation up to 150°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the device's performance and consider thermal management techniques such as heat sinking and airflow to ensure reliable operation.
  • To protect the LT3990 from input voltage surges and transients, consider adding a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input. Additionally, ensure that the input capacitor is rated for the maximum expected input voltage surge.
