LMC7660IMX/NOPB datasheet by Texas Instruments

LMC7660IMX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LMC7660?
  The maximum input voltage that can be applied to the LMC7660 is 12V, but it's recommended to keep it below 10V for reliable operation.
• How do I ensure the LMC7660 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a 10uF capacitor at the output, and add a 1uF capacitor at the input. Also, keep the input and output capacitors close to the device.
• What is the minimum input voltage required for the LMC7660 to operate?
  The minimum input voltage required for the LMC7660 to operate is 3.5V, but it's recommended to keep it above 4V for reliable operation.
• Can I use the LMC7660 as a voltage doubler?
  Yes, the LMC7660 can be used as a voltage doubler, but it's not recommended as it's not optimized for this application. Instead, consider using a dedicated voltage doubler IC.
• How do I calculate the output voltage of the LMC7660?
  The output voltage of the LMC7660 is approximately equal to the input voltage minus 1.5V. For example, if the input voltage is 5V, the output voltage would be around 3.5V.
