L6920D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L6920D?
  The maximum input voltage that can be applied to the L6920D is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L6920D is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a 10nF capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the L6920D to operate?
  The minimum input voltage required for the L6920D to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the L6920D in a high-temperature environment?
  The L6920D is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the L6920D?
  The output voltage of the L6920D can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.25V), and R1 and R2 are the resistors in the feedback network.
