NCS29001数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The NCS29001 is an integrated LED driver used in LCD display backlighting applications. A configurable bill of materials allows the designer to create a highly efficient solution for a variety of LCD screen sizes. The NCS29001 uses a boost type converter to deliver constant current in a string of LEDs. High accuracy PWM dimming is supported for a frequency up to 500 Hz . The integrated soft start function provides excellent control during the power up sequence to avoid current overshoot. The device protects against output overvoltage, open and short LED, and thermal overload. The NCS29001 is offered in the cost effective SOIC14 package.

简介

NCS29001属于集成电路（IC）的LED驱动器。由制造生产的NCS29001LED 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。
