LT3690HUFE#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. Keep the input and output capacitors close to the IC and use short, wide traces for the power paths.
-
Use the datasheet's compensation network design guidelines and adjust the values based on your specific input and output voltage, output current, and desired transient response. You can also use Analog Devices' LTpowerCAD software to help with the design.
-
The maximum junction temperature rating is 125°C. Ensure that the device is properly heat-sunk and that the thermal design is adequate to keep the junction temperature below this rating.
-
Yes, the LT3690HUFE#PBF is qualified for automotive and high-reliability applications. However, additional testing and validation may be required to meet specific industry standards or customer requirements.
-
Follow proper PCB layout and design guidelines, use shielding and filtering as needed, and ensure that the device is properly decoupled and bypassed. Additionally, consider using a common-mode choke and/or a ferrite bead to reduce EMI emissions.
