BCR402R数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The BCR402R is a cost efficient LED driver to drive low power LEDs.

特性 Features

• LED drive current of 20mA
• Output current adjustable up to 60mA with external resistor
• Supply voltage up to 18V
• Easy paralleling of drivers to increase current
• Low voltage overhead of 1.2V
• High current accuracy at supply voltage variation
• No EMI
• Reduced output current at higher temperatures - negative thermal coefficient of -0.3% / K
• RoHS compliant (pb-free) SOT143R package
• Qualified according AEC Q101

优势:
• Homogenous light output despite varying forward voltages in different LED strings
• Homogenous light output of LED’s despite voltage drop across long supply lines
• Homogenous light output independent from supply voltage variations
• Longer lifetime of the LED’s due to reduced output current at higher temperatures (negative thermal coefficient)

应用 Application

• Channel letters for advertising, LED strips for decorative lighting
• Aircraft, train, ship illumination
• Retrofits for general lighting, white goods like refrigerator lighting
• Medical lighting

简介

BCR402R属于集成电路（IC）的LED驱动器。由制造生产的BCR402RLED 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。
