Specifically, the INN2125K-TL is an AC/DC converter and an offline switcher, which makes it ideal for use in a range of applications. In this article, we will explore the applications of the INN2125K-TL, as well as its working principle.

Applications of the INN2125K-TL

The INN2125K-TL is a versatile device, and can be used in a variety of applications. It is most commonly used in consumer and industrial applications, where it is used to provide power to electronic devices. In consumer applications, the device can be used to power consumer electronics, such as DVDs, computers, and gaming consoles. In industrial applications, it is commonly used to power industrial machinery and equipment, such as pumps, motors, and conveyor systems.

The INN2125K-TL is also used in automotive applications, where it is used to power navigation systems, dashboard displays, and other electronic systems. Additionally, it can be used to power medical devices, such as pacemakers and MRI machines. Finally, the device can also be used in wireless communication systems, such as cell phones, Wi-Fi routers, and satellite terminals.

Working Principle of the INN2125K-TL

The INN2125K-TL is a hybrid AC/DC converter and offline switcher, and it works by converting high input voltages (230 Vac) into a low, regulated output voltage (24 Vdc). To do this, the device utilizes a variety of components, such as a bridge rectifier, a filter capacitor, an input-line power factor correction (PFC) circuit, and a half-bridge converter. The bridge rectifier is used to convert the AC input voltage to a DC voltage.

The filter capacitor is then used to smooth out any irregularities in the DC output voltage. The input-line PFC circuit is then used to regulate the input voltage and reduce harmonic distortion. Finally, the half-bridge converter is used to convert the higher input voltage to a low, regulated output voltage. The output voltage is then regulated to produce a constant output current.

Conclusion

The INN2125K-TL is a versatile device, and it can be used for a wide range of applications, ranging from consumer electronics to automotive and medical applications. It is an excellent example of a PMIC, as it combines the functions of an AC/DC converter and an offline switcher to provide a low, regulated output voltage. Its working principle is also relatively straightforward, as it uses key components such as a bridge rectifier, a filter capacitor, and an input-line PFC circuit to convert the higher input voltage to a lower, regulated output voltage.
