Working Principles

The NCP6914AFCDT1G utilizes a synchronous buck converter to efficiently convert the input voltage to the desired output voltage. The integrated control circuitry regulates the output voltage based on the feedback received from the FB pin. The enable pin (EN) allows for easy on/off control of the IC.

During operation, the NCP6914AFCDT1G continuously monitors the output current and temperature. If an overcurrent condition is detected, the IC shuts down to protect itself and the connected devices. Similarly, if the temperature exceeds a certain threshold, the thermal shutdown feature activates to prevent damage.
