LT8302MPS8E#PBF Frequently Asked Questions (FAQ)
-
The LT8302 can handle input voltages up to 80V, but it's recommended to limit the input voltage to 60V for optimal performance and reliability.
-
To minimize EMI, it's recommended to 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 pin) away from sensitive analog nodes.
-
The recommended PCB layout for the LT8302 involves placing the input capacitors (CIN) close to the VIN pin, the output capacitors (COUT) close to the VOUT pin, and using a solid ground plane to reduce noise and EMI.
-
When selecting an inductor for the LT8302, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100mΩ.
-
The LT8302 can deliver up to 2A of output current, but the actual output current capability depends on the input voltage, output voltage, and thermal conditions.
