LT3942JUFD#PBF Frequently Asked Questions (FAQ)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.

  • Ensure that the input voltage rises monotonically and does not droop during start-up. Also, add a soft-start capacitor to the EN pin to control the turn-on time and prevent inrush currents.

  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this limit may affect the device's performance and reliability.

  • Yes, the device is rated for operation up to 125°C junction temperature. However, ensure that the PCB and surrounding components are also rated for high-temperature operation.

  • Check the PCB layout for noise coupling and ensure that the input and output capacitors are properly decoupled. Also, verify that the feedback loop is properly compensated and the device is operated within its recommended operating conditions.
