PMIC or power management integrated circuits are crucial components in all types of electronic devices ranging from consumer products to industrial applications. The XC6119C17A7R-G is a regulator IC produced by the Japanese manufacturer, XCEL Corp. This multi-channel device is designed to control multiple power sources and adapt them to a wide variety of applications, making it a highly versatile piece of hardware. In this article, we will explore its capabilities and discuss the XC6119C17A7R-G’s application field and working principle.

The XC6119C17A7R-G is a multi-channel regulator IC that consists of two separate parts: a primary regulator, and an auxiliary regulator. The primary regulator is responsible for providing up to six regulated voltage outputs, while the auxiliary regulator is responsible for providing up to three regulated outputs. Combined, these two regulators are capable of providing up to nine regulated voltage outputs.

The primary output voltage is set by a single adjustable voltage source. This voltage source has a range of 0.7V to 24.5V, and can be adjusted in increments of 0.1V. The auxiliary output voltage is set by two additional adjustable voltage sources that have a range of 0.7V to 15V, and can be adjusted in increments of 0.05V. The XC6119C17A7R-G has a switching frequency of up to 2.1MHz, which can be adjusted down to a minimum of 400kHz.

The XC6119C17A7R-G is ideal for applications such as motor control, automotive electronics, home appliance control, and industrial electronics. It can be used to control the voltage of DC motors, to provide constant voltage and current to automotive systems, to regulate power supply for home appliances, and to provide control for industrial electronics. Furthermore, it is also compatible with many communication protocols, allowing it to be easily incorporated into a wide range of systems.

Now that we’ve discussed its application field, let’s take a look at how the XC6119C17A7R-G works. This regulator is a two-stage device, meaning it uses two distinct stages to regulate the output voltage. First, the input voltage is conditioned in the front-end stage, which consists of an inductor and a capacitor connected in series. This filter stage removes any transients, ensuring that the output voltage is as clean as possible.

The second stage of the XC6119C17A7R-G is the control loop stage, which is responsible for maintaining the output voltage within a certain range. This stage is composed of a power MOSFET and a current-sense resistor, both of which are connected in series to the output terminal. The current-sense resistor measures the current flow through the MOSFET, while the MOSFET regulates the current flow with the help of a PWM signal. This PWM signal is generated by the regulator IC and is used to control the on-time duration of the MOSFET, thus controlling the output voltage.

Finally, the XC6119C17A7R-G is equipped with a wide selection of protection and safety features, including overvoltage, overcurrent, thermal shutdown, and fault-logging. These features help protect the circuit from damage and ensure reliable operation in the long run.

In conclusion, the XC6119C17A7R-G is an ideal regulator for such applications as motor control, automotive electronics, home appliance control, and industrial electronics. Its two-stage design ensures clean output voltages, while its array of protection and safety features provide reliable operation. Furthermore, its adjustable voltage sources and wide range of communication protocols make it perfect for a variety of applications.
