NCP3063BPG is a DC/DC switching regulator IC that provides a cost effective and very efficient solution for the current step-down DC/DC converters which become increasingly popular for communications and portable electronic products. The NCP3063BPG is specifically designed for automotive, telecommunication, notebook and other portable electronic applications. The NCP3063BPG integrated circuit provides power conversion from an input voltage of 2.7V to 5.5V to a very low output voltage. The NCP3063BPG provides a full featured double pulse width modulation (PWM) controller with synchronous rectification, low RDS(ON) output MOSFET and a wide input voltage range. It allows the designer to meet stringent energy efficiency requirements. It is suitable for the higher efficiency application across a wide range of input voltages with very low power loss.

The NCP3063BPG application field includes multiple automotive, industrial and communication fields. In automotive areas, it can be used in car electronics such as car navigation and audio system, on-board charger, DC/DC converters, and others. In industrial areas, it can be used in the PFC control of the ac/dc switching adaptor, DC/DC converters, notebook power management, power system and so on. In communication fields, it can be used in GSM/EDGE, HSDPA/CDMA, WiMAX/Wi-Fi or other wireless access. All these application fields can use the NCP3063BPG DC/DC switching regulator as an effective solution.

The working principle of the NCP3063BPG is simple: the input voltage is applied to the primary side of the power transformer and then the secondary side of the transformer transfers energy to the output. This energy transfer is made possible by the built-in PWM controller and synchronous rectifier which converts the input voltage to the desired output voltage. The PWM controller works by controlling the transistor switch of the transformer coil and the synchronous rectifier converts the transformed alternating current to direct current. The current flowing through the output is thus regulated by regulating the PWM controller, the switching frequency of the PWM controller and the voltage drop of the synchronous rectifier. The NCP3063BPG also has a wide input voltage range that allows it to efficiently convert any voltage up to 5.5V into a lower one.

In summary, the NCP3063BPG is a DC/DC switching regulator IC which is suitable for multiple application fields and provides a cost effective, efficient and reliable solution for current step-down DC/DC converters. It utilizes a full featured double pulse width modulation (PWM) controller with synchronous rectification, low RDS(ON) output MOSFET, and a wide input voltage range. All these characteristics make NCP3063BPG a perfect choice for automotive, telecommunication, notebook and other portable electronic applications.
