BCR601数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

BCR601 is a linear LED controller IC regulating the LED current with an external driver transistor. It supports either NPN bipolar transistors or N-channel MOSFETs to cover a wide LED current and power range up to several amperes. The LED current is fully scalable by dimensioning an external resistor at MFIO pin.
A unique feature of BCR601 is to provide feedback to the primary side via an optocoupler to control the output voltage of the primary side converter, e.g. XDPL8218. The integrated control loop minimizes the voltage overhead and power dissipation of the external driver transistor. This capability, coupled with the adjustment of voltage overhead by external configuration according to application needs, leads to efficient LED systems.
AC line ripple suppression, analog dimming option and various protection features round up this device for LED drivers allowing for flicker-free light and longevity of LEDs.

简介

BCR601属于集成电路（IC）的LED驱动器。由制造生产的BCR601LED 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。
