L6928D datasheet by STMicroelectronics

L6928D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L6928D?
  The maximum input voltage that can be applied to the L6928D is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L6928D 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 small ceramic capacitor (around 100nF) between the VIN and GND pins.
• What is the minimum input voltage required for the L6928D to operate?
  The minimum input voltage required for the L6928D to operate is around 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the L6928D in a high-temperature environment?
  The L6928D is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the L6928D?
  The output voltage of the L6928D can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (around 2.5V), R1 is the feedback resistor, and R2 is the divider resistor.
