PMIC (Power Management IC) plays an important role in the AC DC converters, offline switchers and other exposed electrical and electronic devices. This article will discuss the application field and working principle of NCP1218AD65R2G, a PWM controller.NCP1218AD65R2G is a low-cost, high-performance, single-phase pulse width modulation (PWM) controller with standby, short-circuit and thermal protection features. It is typically used in isolated DC/DC, AC/DC and switch mode power supply (SMPS) off-line applications, including desktop computers and LCD TVs.

The ultra-low start-up current of the NCP1218AD65R2G makes it ideal for standby applications, while its low regulating memory provides low output ripple. Moreover, thanks to its over-temperature protection, the device can be used in a wide range of off-line applications. It is also suitable for LED applications when the LED current is varied to provide brightness adjustment.

The main application fields for the NCP1218AD65R2G are DC/DC, AC/DC, SMPS and LED lighting applications. The main target of this device is to provide a low-cost, low-voltage, high-performance solution for these applications. It is designed with a wide range of operating conditions, from 5V to 65Vdc and up to 500kHz switching frequency.

The working principle of NCP1218AD65R2G is the same as that of most PWM controllers. It uses a pulse width modulation technique to control the voltage in the application. When an input signal is received, the NCP1218AD65R2G converts the signal into a pulse width modulation signal. This signal is then used to control the current flow through a switch. The current flow is then regulated by varying the width of the pulses. As the pulse width increases or decreases, the output voltage is also adjusted.

In addition to the pulse width modulation, the NCP1218AD65R2G also uses a variety of other techniques to provide a high-performance output. For example, it employs an under-temperature protection feature to ensure that the output remains consistent even if the device is operated at high temperatures. It also has an over-current protection feature that helps to protect the components from damage due to excessive input current.

The NCP1218AD65R2G was designed to meet a wide variety of needs, from low-voltage to high-voltage applications. It is well-suited for use in DC/DC, AC/DC, SMPS and LED lighting applications. Thanks to its low start-up current and over-temperature protection, the device is a great choice for off-line applications. Moreover, its ultra-low regulating memory provides excellent output ripple management.
