描述 Description

The ZXLD1374 is a 60V LED driver with integrated 1.5A low side switch to drive high current LEDs. It is a multi-topology converter enabling it to operate in Buck, Boost and Buck-boost configurations; efficiently controlling the current of up to 16-series connected LEDs. The ZXLD1374 is a modified hysteretic converter using a patent pending control scheme providing high output current accuracy in all three topologies. High accuracy dimming is achieved through DC control and high frequency PWM control. The ZXLD1374 uses two pins for fault diagnosis. A flag output highlights a fault, while the multi-level status pin gives further information on the exact fault. The ZXLD1374 has been qualified to AEC-Q100 Grade 1 enabling operation in ambient temperatures from -40 to +125°C.

简介

ZXLD1374属于集成电路（IC）的LED驱动器。由制造生产的ZXLD1374LED 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。
