LTM8055IY Frequently Asked Questions (FAQ)
-
The LTM8055IY can handle input voltages up to 40V, but it's recommended to keep it below 36V 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 components away from the low-frequency components. Also, use a shielded inductor and keep the PCB layout symmetrical.
-
The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor is recommended to reduce EMI. The inductor type should be a low-loss, high-current inductor with a high saturation current rating.
-
The output voltage of the LTM8055IY can be adjusted by changing the resistor divider ratio of the feedback resistors (R1 and R2). The output voltage can be calculated using the formula: Vout = 0.8V * (1 + R2/R1).
-
The LTM8055IY can deliver up to 5A of output current, but it's recommended to keep it below 4A for optimal performance and reliability.
