Working Principle

The NCP5318FTR2 series regulators are switching devices that operate on the principle of pulse-width modulation (PWM). These regulators utilize an internal oscillator to generate a PWM signal which is then converted into an AC signal. This signal is then used to power the output devices which allows the user to adjust the output voltage to the desired level. The device also features various protective features such as thermal shutdown, over-current protection and frequency synchronization. These protective features help prevent damage to the device or the system.

Conclusion

The NCP5318FTR2 series of special purpose voltage regulators provide an adjustable and efficient output voltage for a wide variety of applications. They are suitable for boosting, bucking and inverting applications, and also feature protective features such as thermal shutdown, over-current protection and frequency synchronization. These features ensure the device is reliable and safe to use.
