The maximum input voltage that can be applied to the ICL7665CSA+T is 12V, but it's recommended to keep it below 10V for reliable operation.
Yes, the ICL7665CSA+T can be used as a voltage doubler, but it's not recommended as it's not optimized for this application. The device is designed for voltage inversion and voltage multiplication.
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.
The maximum output current that the ICL7665CSA+T can provide is 20mA, but it's recommended to keep it below 10mA for reliable operation and to avoid overheating.
The ICL7665CSA+T is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 100°C for reliable operation. Make sure to provide adequate heat sinking and thermal management.
