NCP5603GEVB

The NCP5603GEVB is an evaluation board for NCP5603 charge pump converter/white led driver. The NCP5603 is dedicated to the medium power white LED applications. The power conversion is achieved by means of a charge pump structure, using two external ceramic capacitors, making the system extremely tiny. The NCP5603 supplies a constant voltage to the load from a low battery voltage source and it is particularly suited for the high efficiency LED used in low cost, low power applications, with high extended battery life. This evaluation board describes a multi functional system, capable of generating and controlling the power needed to utilized three features available in modern cellular phones. In addition to larger displays, with full color capability, flash and torch features have now been added to support the embedded camera and the night path finder. These features are made possible by using an ultra bright LED powered by standard battery cells.
