AP5724中文资料low-voltage-dc-dc-led-drivers数据手册Diodes规格书

描述 Description

This is a Boost LED driver designed drive white LED with constant current. It can drive 2 ~ 6 LED in a series connection from a single Li-Ion cell ensuring uniform brightness in small screen backlighting applications. The device also supports a single feedback of parallel connected multiple strings of LEDs for driving higher number of LEDs. It is available in SOT26, low profile TSOT26 and the extremely thin and small footprint U-DFN2020-6 Type C.

简介

AP5724属于集成电路（IC）的LED驱动器。由制造生产的AP5724LED 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。
