设计
NCP1050 至 NCP1055 为单片高稳压器,可使最终产品设备符合低待机功耗要求。该器件系列组合了所需的转换器功能,为办公室自动化、消费品和工业产品提供了一个简单经济的电源系统方案。 此类器件适用于直接采用整流交流线路电源运行。在反激转换器应用中,对于固定交流输入 100 V、115 V 或 230 V,它们能够提供 6.0 W 至 40 W 的输出功率,对于 85 V 至 265 V 的可变交流输入,则能提供 3.0 W 至 20 W 的输出功率。 此器件系列具有有源启动稳压器电路,无需在转换器变压器上设置辅助偏置绕组,还具有采用可编程计时器的故障逻辑用于实现过载保护,独特的门控振荡器配置用于带双脉冲抑制的极快环路响应,电源开关电流限制,带磁滞的输入欠压锁定,高温关断和自动重启故障检测。此类器件采用经济型 8 引脚双列直插封装。
