NCP5603中文资料White LED Driver, High Efficiency, Charge Pump Converter数据手册ONSEMI规格书

描述 Description

The NCP5603 is an integrated circuit dedicated to the medium power White LEDapplications. The power conversion is achieved by means of a charge pump structure,using two external ceramic capacitors, making the system extremely tiny.The device supplies a constant voltage to the load from a low battery voltage source. It is particularly suited for the High Efficiency LED used in low cost, low power applications, with high extended battery life.

简介

NCP5603属于集成电路（IC）的LED驱动器。由制造生产的NCP5603LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
