The maximum input voltage that can be applied to the ICL7663ACSA+ is 12V, but it's recommended to keep it below 10V for reliable operation.
No, the ICL7663ACSA+ 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.
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 ICL7663ACSA+ is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
To protect the ICL7663ACSA+ from input voltage transients, use a voltage clamp or a transient voltage suppressor (TVS) diode at the input. This will help prevent damage to the device from voltage spikes or surges.
