LT3688IUF#PBF Frequently Asked Questions (FAQs)
The maximum input voltage that can be applied to the LT3688 is 36V, but it's recommended to keep it below 30V 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-current paths short and direct. Also, use a shielded inductor and orient it to minimize radiation.
The recommended PCB layout for the LT3688 is to keep the input and output stages separate, use a star-ground configuration, and keep the sensitive analog signals away from the high-current paths.
To select the right inductor for the LT3688, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current of at least 1.5 times the maximum output current.
The maximum output current that the LT3688 can deliver is 3.5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
