NCP3064BDR2G is a type of DC DC Switching Regulator which is used in various fields. It has an advanced high-efficiency regulation, fast transient response and low output noise characteristics which make it suitable for portable computers, personal digital assistance (PDA), camera, radio, and GPS applications. The device is available in a compact SOT-23-5 package, making it suitable for space saving applications.

The NCP3064BDR2G is a buck-boost converter using a switching mode approach so as to convert input voltage to the desired output voltage. It is a synchronous step-down regulator for output current of up to 600mA, designed for use with input voltage ranging from 1.8V up to 5.5V. It consist of an integrated low side power switch,passive components, 3.2V internal reference, feedback circuitry and an on-chip control logic.

The NCP3064BDR2G exhibits very high efficiency which can reach up to 96%. This makes the device ideal for applications that require long battery life, high efficiency and low ripple. The device incorporates power saving shutdown mode,low quiescent current and active output voltage discharge. It also provides excellent load and line regulation, wide input/output range and thermally protected circuitry to ensure improved reliability and safety.

The NCP3064BDR2G employs high-side N-channel power MOSFET and low-side P-channel MOSFET and generates high precise output, which is the major feature of all buck-boost regulators. It employs patented automatic phase wall hourglass control technique, which reduces the input ripple current and so reduces power loss.The features of NCP3064BDR2G make it popular in portable device applications such as PDA, handheld computers, Notebook computers, and so on.

The working principle of the NCP3064BDR2G DC DC Switching Regulator can be described as follows. A MOSFET switch is driven in periodic switching mode by either a voltage at its gate or current, so that charge is alternately stored and discharged from an inductor to the output load or capacitor. It runs at a constant frequency and switches from its high state to its low state, or vice versa. The device uses an internal logic control to control the switching frequency depending on the input and output voltages, current and temperature. This ensures that the requested output voltage level is obtained and that no external extra components are required.

In conclusion, the NCP3064BDR2G DC DC Switching Regulator is an excellent device for applications like LCD displays, PDAs, handheld computers, Notebook computers, and so on. It has features such as high efficiency, low ripple current, very low quiescent current, and low noise, making it suitable for those applications. Its high output accuracy, internal current limit, and overload protection also make it very reliable.
