L5986A Frequently Asked Questions (FAQ)
-
The L5986A can handle a maximum input voltage of 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
-
The L5986A operates within a stable temperature range of -40°C to 150°C. Ensure good thermal design, use a heat sink if necessary, and avoid overheating to prevent damage.
-
Use a multi-layer PCB, keep the input and output tracks separate, and use a ground plane to minimize EMI and noise. Also, place the input and output capacitors close to the IC and use a shielded inductor.
-
Choose an inductor value based on the output voltage, output current, and switching frequency. A general rule of thumb is to use an inductor with a value between 10uH to 47uH for most applications.
-
The bootstrap capacitor is used to generate the high-side gate drive voltage for the internal MOSFET. It's essential for proper operation and should be chosen based on the output voltage and switching frequency.
