The recommended operating voltage range for the UC1707L is 12V to 18V, although it can operate up to 20V with reduced performance.
To ensure proper biasing, connect a 1kΩ to 2kΩ resistor between the VCC pin and the VIN pin, and a 10kΩ to 20kΩ resistor between the VCC pin and ground.
The UC1707L can deliver up to 1.5A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions.
Use a voltage regulator or a voltage supervisor IC to monitor the input voltage and shut down the UC1707L if it exceeds the recommended operating range.
The EN pin is used to enable or disable the UC1707L. When the EN pin is high, the device is enabled, and when it is low, the device is disabled.
