LTC3633AEUFD-1#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
-
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., LX) away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
-
A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 10uF to 22uF is recommended for the output capacitor. The exact value depends on the specific application requirements and output voltage ripple tolerance.
-
The output voltage can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula: VOUT = 0.8V x (1 + R2/R1) to calculate the desired output voltage.
-
The maximum ambient temperature range for the LTC3633AEUFD-1#PBF is -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures.
