The maximum input voltage that can be applied to the LTC3526 is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
To optimize inductor selection, consider the inductor's saturation current, DC resistance, and core loss. A good starting point is to choose an inductor with a saturation current at least 1.5 times the peak current, and a DC resistance less than 100mΩ.
For optimal performance, keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise and EMI. Also, keep the high-frequency switching nodes (e.g., LX and SW) away from sensitive analog nodes.
The output voltage of the LTC3526 can be adjusted by changing the resistive divider ratio of the feedback resistors (RFBT and RFBG). Use the formula VOUT = 0.8V x (1 + RFBT/RFBG) to calculate the desired resistor values.
The maximum ambient temperature range for the LTC3526 is -40°C to 125°C, but the device's performance and reliability may degrade at extreme temperatures. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
