描述 Description

The ZXLD1350Q is a hysteretic mode inductive step-down converter with integrated switch and high side current sense. It operates from an input supply from 7V to 30V driving single or multiple series connected LEDs efficiently external adjustable output current up to 350mA. The output current can be adjusted by applying a DC voltage or a PWM waveform. 100:1 adjustment of output current is possible using PWM control. Applying a voltage of 0.2V or lower to the ADJ pin turns the output off and switches the device into a low current standby state. The ZXLD1350Q has been qualified to AECQ100 grade 2 and is Automotive Grade supporting PPAPs.

简介

ZXLD1350Q属于集成电路（IC）的LED驱动器。由制造生产的ZXLD1350QLED 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。
