LT3690MPUFE#TRPBF Frequently Asked Questions (FAQ)
-
A good PCB layout is crucial for the LT3690's performance. Keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise. Also, keep the high-current paths short and wide to minimize resistance and inductance.
-
Choose input capacitors with low ESR and high ripple current rating to minimize voltage ripple. For output capacitors, select ones with low ESR and high capacitance to ensure good load transient response. X5R or X7R ceramic capacitors are good options.
-
The LT3690 is rated for operation up to 125°C junction temperature. However, for reliable operation, it's recommended to keep the ambient temperature below 85°C to ensure a safe margin.
-
To ensure stability, follow the recommended component values and PCB layout guidelines. Also, make sure the input and output capacitors are properly selected, and the feedback network is correctly configured.
-
The LT3690 can deliver up to 3A of output current, but this depends on the input voltage, output voltage, and thermal conditions. Be sure to check the datasheet's thermal derating curves to determine the maximum output current for your specific application.
