With its dual-channel, one-port architecture, the NCP1380DDR2G offers a wide range of output voltage ranges. This includes an adjustable (0V to 6V) and non-adjustable (3.3V to 18V) in buck-boost configuration and a range of fixed outputs for AC/DC and DC/DC applications.

Working Principle：

The NCP1380DDR2G utilizes Pulse Width Modulation (PWM) to control the current flow in a power supply. The output current is proportional to the duty cycle of the PWM pulse, which is varied by the internal PWM controller. The PWM controller is designed to operate from a low voltage input and a wide range of output currents by varying the on-time of the PWM output. The NCP1380DDR2Gis designed to provide high frequency switching with low-noise operation. In addition, the device is equipped with internal protection features that enable safe operation in the event of a load or system fault.

The NCP1380DDR2G uses dynamic frequency control to ensure a constant switching frequency under a wide range of load conditions. This technology is designed to maintain the stability of the system while providing maximum power conversion efficiency and enhancing the overall system reliability. The device also features integrated output voltage sensing circuitry which improves the precision of the output voltage regulation. Finally, the NCP1380DDR2G incorporates an adjustable soft-start function that allows the device to ramp up the output current slowly, reducing system inrush current and enabling an overall smoother system transition.

In summary, the NCP1380DDR2G is a high-performance IC designed to support modern digital systems. It is well suited for power conversion applications in distributed bus systems, small audio systems, and server applications. The NCP1380DDR2G features a wide range of output voltage ranges, dynamic frequency control, and internal protection features that enable safe operation in the event of a system fault. Its adjustable soft-start function and integrated output voltage sensing also enables smooth system transitions and improved precision of the output voltage regulation.
