ICL7663AESA+ datasheet by Maxim Integrated Products

ICL7663AESA+ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the ICL7663AESA+?
  The maximum input voltage that can be applied to the ICL7663AESA+ is 12V, but it's recommended to keep it below 10V for reliable operation.
• Can I use the ICL7663AESA+ as a voltage doubler?
  No, the ICL7663AESA+ is a voltage converter, not a voltage doubler. It can only convert a positive input voltage to a negative output voltage, but it cannot double the input voltage.
• How do I ensure the output voltage is stable and regulated?
  To ensure the output voltage is stable and regulated, make sure to use a suitable output capacitor (e.g., 10uF) and a minimum load current of 1mA. Also, keep the input voltage within the recommended range and avoid overloading the device.
• Can I use the ICL7663AESA+ with a switching power supply as the input source?
  Yes, but with caution. The ICL7663AESA+ can be sensitive to high-frequency noise and ripple from switching power supplies. Add a filter capacitor (e.g., 10uF) at the input to reduce noise and ensure reliable operation.
• What is the maximum output current that the ICL7663AESA+ can provide?
  The maximum output current that the ICL7663AESA+ can provide is 20mA. Exceeding this current may cause the device to overheat or malfunction.
