按技术分类
NCP1250 是一款高度集成的 PWM 控制器,能够在极小型 TSOP-6 封装内提供耐用的高性能离线电源。该控制器供电范围高达 28 V,具有带抖动的 65 kHz 或 100 kHz 开关电路,在峰值电流模式控制下运行。当辅助侧功率开始降低时,该控制器将其开关频率自动折回至最低 26 kHz 的水平。当功率进一步下降时,该零部件进入跳过周期,同时对峰值电流进行限制。 40W 适配器过功率保护 (OPP) 是一种非常困难的措施,尤其当无负载待机要求驱动转换器规格时更是如此。安森美半导体的专属集成 OPP 让您仅通过两个外部电阻即可充分利用提供的最高功率,而不会影响待机性能。同一个引脚上还组合了过电压保护输入,用于在发生光耦合器故障或反向开路运行时保护整个电路。最后,基于计时器的短路保护提供了最佳保护方案,让您能够精确选择保护跳闸点,而不用考虑辅助绕组和电源绕组之间的松散耦合。
