LT3690MPUFE#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT3690 is 40V, but it's recommended to keep it below 36V for reliable operation.
-
To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
-
The recommended operating temperature range for the LT3690 is -40°C to 125°C, but the junction temperature should not exceed 150°C.
-
Yes, the LT3690 is qualified for automotive and high-reliability applications, but you should consult the datasheet and relevant standards (e.g., AEC-Q100) to ensure compliance with specific requirements.
-
To troubleshoot issues with the LT3690, check the input and output voltage levels, ensure proper decoupling and filtering, and verify that the layout and component selection meet the datasheet recommendations. You can also use simulation tools or consult with Linear Technology's application support team.
