L6920DTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L6920DTR?
  The maximum input voltage that can be applied to the L6920DTR is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L6920DTR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the L6920DTR to operate?
  The minimum input voltage required for the L6920DTR to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the L6920DTR in a high-temperature environment?
  The L6920DTR 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 L6920DTR?
  The output voltage of the L6920DTR can be calculated using the formula: Vout = 1.235 x (1 + R2/R1), where R1 and R2 are the resistors connected to the FB pin.
