Working Principle of NX2114CSTR Voltage Regulator

The NX2114CSTR Voltage Regulator operates in a constant on-time (COT), peak current mode control architecture. This topology utilizes a high side MOSFET switching the output voltage from the input voltage source. When the output voltage drops below the preset level, the NX2114CSTR will constantly monitor the output voltage, and adjust the MOSFET on-time accordingly to maintain the output voltage. This on-time will remain constant regardless of the load current, and this provides good stability over a wide range of load conditions.

When the output voltage rises higher than the preset level, the NX2114CSTR will respond by decreasing the on-time of the MOSFET, preventing any over-voltage conditions. Additionally, the device also provides programmable soft-start and protection against over temperature, input under voltage, and output short circuit conditions.
