Features of NCP1351CPG

The NCP1351CPG has a number of features that make it an ideal power solution for AC-DC and DC-to-DC converters:- Integrated Current Mode Controller: The integrated current mode controller enables regulation of normal and stand-by output voltages, with protection features including frequency jitter, over-voltage lockout, under-voltage lockout, over-temperature protection, and soft-start.- Wide Output Voltage Range: The output voltage range of the NCP1351CPG ranges from 0.8V-21V with 0.7V accuracy and 0.2V setting resolution.- High Efficiency: With up to 97.6% efficiency, the NCP1351CPG offers excellent energy savings compared to other solutions.- Low Current Start-up: The NCP1351CPG has a low start-up current of 18uA, allowing for low power consumption at start-up and standby.

Working Principle

The NCP1351CPG works based on the principle of Pulse Width Modulation (PWM). The integrated current-mode controller monitors the output voltage and adjusts the duty cycle of the PWM signal to maintain voltage regulation.When the NCP1351CPG is activated, the integrated current-mode controller sends a pulse width modulated (PWM) signal to the Power Stage MOSFETs. The Duty Cycle of this PWM signal is based on the input voltage, the output voltage, and an external compensation circuit. When the PWM signal is activated, it causes the Power Stage MOSFETs to switch on and off at a high speed. This switching allows the converter to achieve excellent power conversion efficiency and clean output voltages.When the load fluctuates, the current-mode controller constantly adjusts the duty cycle of the PWM signal so that the voltage remains within the desired range. This helps to ensure efficient and reliable power conversion, even during load fluctuations.

Applications

The NCP1351CPG is well-suited for a variety of AC-DC and DC-DC applications, including:- AC-DC Power Supplies- DC-DC Converters- Battery-powered Systems- Notebook PC Power Supplies- Power Management Systems- Industrial Control Systems.The NCP1351CPG is also well-suited for automotive and automotive-related applications, where higher efficiency, lower emissions and improved system design can be achieved.

Benefits

The NCP1351CPG offers a number of benefits, including efficient power conversion, clean output regulation, wide output voltage range and improved system design. The integrated current-mode controller helps to ensure efficient power conversion and clean regulation, while the low start-up current helps to reduce power consumption at start-up and standby.
