NCV8163ASN180T1G is a polyphase energy efficient synchronous buck regulator. It is ideal for applications that require low profile, low noise and good load transient performance. The polyphase operation enables the shift from load sharing to droop control in needed load current range. The buck regulator is capable of providing up to 10A of output current with output voltage tracking feature.

The NCV8163ASN180T1G is a monolithic integrated buck regulator, specifically designed for low voltage, low power applications. It integrates two high efficiency buck regulators in a single package. The two channels can be configured to operate independently in buck, or cascaded in a buck-boost configuration. The device is also capable of providing active tracking of one output against the other.

The NCV8163ASN180T1G buck regulator operates with an input voltage from 2.5V to 6V, providing an adjustable output voltage from 0.8V to 5V with either a single 100 mV or 0.5% accurate external reference. The device supports adjustable current over-temperature limits and over-current smoothing protection capabilities. Additionally, a programmable soft start time is available for both channels, preventing inrush current.

The application field of NCV8163ASN180T1G can be widly used in automotive, industrial, and consumer applications which require high current, low noise, and good load transient performance use cases. It is suitable for applications such as automotive infotainment systems, display backlight driver, industrial process control systems, and RF power amplifiers.

The working principle of the NCV8163ASN180T1G is to regulate the output voltage by measuring the actual output voltage and comparing it to the reference voltage. The internal feedback loop compares the actual output voltage to the reference voltage and adjusts the duty cycle of the switch accordingly to maintain the voltage across the load. The device can be configured in either buck, buck-boost, or shift-buck topology, depending on the application.

The buck topology is the most common configuration and is used when the input voltage is higher than the desired output voltage. In the buck configuration, the device pulls the output voltage down by switching the current through the output inductor on and off, resulting in an average voltage level. The output voltage can be adjusted by varying the duty cycle of the switch.

The buck-boost topology is used when the input voltage is lower than the desired output voltage, and it is capable of providing up to 150V output voltage. The device works by switching the current through the output inductor on and off, and the inductor charges the voltage up to the desired level. The output voltage can be adjusted by varying the duty cycle.

The shift-buck topology is used when the output current is required to be highly specific, and it is capable of providing up to 450V output voltage. This configuration works similarly to the buck-boost configuration, however, it works by shifting the current through the output inductor, resulting in a better regulation when the output current is low. The output voltage can also be adjusted by varying the duty cycle.

In conclusion, the NCV8163ASN180T1G is a high efficiency synchronous buck regulator that is ideal for low voltage, low power applications. It integrates two high efficiency buck regulators in a single package and is capable of providing up to 10A of output current. It is suitable for applications such as automotive infotainment systems, industrial process control systems, and RF power amplifiers, requiring high current, low noise and good load transient performance. The device works by regulating the output voltage by measuring the actual voltage and comparing it to the reference voltage, and is capable of operating in either buck, buck-boost or shift-buck topology, depending on the application.
