宽输入无传感器CC/CV 1A降压变换器

AT2001是一种宽输入电压、高效率的降压式DC/DC变换器，工作在CV（恒定输出电压）模式或CC（恒定输出电流）模式。\r\nAT2001在135kHz开关频率下提供高达1.3A的输出电流，无需额外的晶体管。\r\n内部无传感器CC控制消除了昂贵的，高精度的电流检测电阻，使之成为理想的电池充电应用和精确的电流限制适配器。\r\nAT2001通过消除外部电流感测电阻器相关的功率损耗，实现了比传统恒流开关稳压器更高的效率。\r\n关于保护功能，热关机是为了防止超温操作损坏；逐周期限流是为了防止开关过电流操作；过压保护（OVP）是为了避免高电压损坏电路和电容器。\r • 宽输入电压，8V~40V工作\r\n• 固定频率135KHZ，易于电磁干扰控制\r\n• AT2001Z高达2.5%输出电压补偿1A输出负载\r\n• 受专利保护的无传感器CC回路控制\r\n• 精密反馈电压1.2V+-1%调节\r\n• SOT23-6封装\r;
