NCP114BMX180TCG Application Field and Working Principle

NCP114BMX180TCG is a power management integrated circuit (PMIC) linear voltage regulator, widely applied in small space and big power system, such as digital display, large computers, communication, and industrial control areas.

Features of NCP114BMX180TCG

NCP114BMX180TCG is a flexible High-Voltage Linear Regulator with separate sense and output terminals. It offers precise output voltage through voltage reference and error amplifier. The NCP114BMX180TCG has an output voltage range of 3V to 24V, and input voltages up to 30V. It features excellent line regulation, fast response times, and very low ripple and noise. Other features include output current limiting, thermal shutdown, and overvoltage protection to guard against incorrect inputs.

Application Fields and Working Principle

NCP114BMX180TCG can be applied for voltage converters and battery flash-drivers, computer and peripherals, LCD display driving, consumer electronics, and automotive equipment.It can be integrate into four part, as follows: pin amplifier, error amplifier, voltage reference, and control logic. The block diagram shows:

The main operating principle of the NCP114BMX180TCG is to compare the voltage of the reference pin with the feedback pin. If the feedback pin is higher than the reference pin, the output of the error amplifier decreases, hence increasing the ON-time of the main switch, thus reducing the voltage at the output pin. If the feedback pin is lower than the reference pin, the output of the error amplifier increases, thus decreasing the ON-time of the main switch and increasing the voltage at the output pin.

Conclusion

NCP114BMX180TCG is an ideal solution for high power and small space applications. It offers reliable, precise and programmable output voltages over a wide voltage range. The features of the NCP114BMX180TCG include excellent line regulation, fast response times, and very low ripple and noise. It also offers excellent protection features such as temperature shutdown and overvoltage protection.
