BCR420UE6433数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

Linear LED driver IC for low/medium power LEDs

特性 Features

• LED drive current preset to 10mA
• Output current adjustable by resistor up to 150mA
• Supply voltage up to 40V
• Low side current control, NPN transistor power stage
• PWM dimmable by external transistor
• Up to 1000mW power dissipation in a small SC74 package
• Negative thermal coefficient reduces output current at higher temperatures
• Automotive qualified according to AEC Q101

优势:
• Driving current always under control for homogenous light output
• Longer lifetime of the LEDs due to reduced output current at higher temperatures (negative thermal coefficient)
• Easy paralleling of drivers to increase current
• Contributes to longevity and reliability of LED system

简介

BCR420UE6433属于集成电路（IC）的LED驱动器。由制造生产的BCR420UE6433LED 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。
