LTM8055MPY Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTM8055MPY is 40V, but it's recommended to keep it below 36V 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 wide. Also, avoid routing sensitive signals near the inductor.
-
The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5 ohms or less) is recommended for optimal performance.
-
The output voltage of the LTM8055MPY can be set using the FB pin and a resistive divider network. The feedback voltage is 0.8V, and the output voltage is determined by the ratio of the resistors in the divider network.
-
The maximum output current of the LTM8055MPY is 5A, but it can be limited by the input voltage, output voltage, and thermal considerations.
