产品概述

描述

ST-ONE是全球首款在单一封装内嵌入Arm Cortex M0+内核、带同步整流功能的离线可编程控制器以及USB PD PHY的数字控制器。该系统能有效控制ZVS非互补有源钳位反激式转换器,可用于构建具有USB-PD接口的高功率密度充电器和适配器。

该器件包括一个有源钳位反激式控制器及其初级侧的高压启动模块、一个微控制器,以及所有控制次级侧转换和USB-PD通信所需的外设。两侧通过内嵌的电气隔离型双通信信道实现连接。通过使用新型非互补式控制技术和专门设计的功率模式,该器件能够同时实现高效率和极低的空载功耗。

该器件具有预加载的固件,用于处理电能转换和USB-PD通信协议,包括可选的PPS和电子标记线缆管理。

专用内存用于存储制造过程中的默认器件配置。用户可以更改或调整该内存区域,以适应最终产品规格。
