LM2578AMX/NOPB Frequently Asked Questions (FAQ)

  • The LM2578 can handle a maximum input voltage of 40V, but it's recommended to keep it below 35V for reliable operation.

  • The inductor value depends on the output current, input voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet (e.g., 22µH for the LM2578). You can also use online inductor selection tools or consult with a TI engineer for more guidance.

  • The minimum input capacitance required is 10µF, but it's recommended to use a higher value (e.g., 22µF) to ensure stable operation and reduce input voltage ripple.

  • The LM2578 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to follow the thermal design guidelines in the datasheet and consider using a heat sink if necessary.

  • To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a 10nF capacitor between the Vout and GND pins. You can also add a 1kΩ resistor between the Vout and Vin pins to improve stability.
