PTH04070WAH 产品描述
3-A,3.3/5-V输入可调节开关稳压器
3.3-V / 5-V输入电压UL/IEC/CSA-C22.2 60950-1
电流限制保护
热关断
PTH04070W
当配置每个标准的应用程序,的PTH04070W功率模块产生一个稳定的输出
一个有效的输入电压源电压下的应用。在上电时,内部软启动电路放缓
率,输出电压的上升,从而限制浪涌电流的量,可以得出从
输入信号源。软启动电路,电源引入了一个很短的时间延迟(一般为10毫秒)
特性。这是一个有效的输入源被确认。图10示出了上电
从3-V输入和输出电压波形的PTH04070W,调整为1.8 V
波形进行测量2-A阻性负载。
图10。上电波形
PTH04070W模块的连续电流限制特性防止负载故障。的负荷下
故障的条件下,输出电流不能超过电流限制值。试图吸取的电流超过
的电流限制值将导致输出电压逐渐减小。电流被连续地供给到
直到故障被删除。搬迁后的故障时,输出电压会迅速恢复。
热关断保护模块的内部电路对过高的温度。的上升
温度可以是下降在空气气流中,高环境温度下,或持续的电流限制的结果
条件。如果交界处的内部部件的温度超过150℃时,该模块关闭。这
输出电压降低到零。该模块将自动启动,启动软启动上电时,
检测到的温度降低10°C以下,热关断的触发点。
Comments: The boss is very timely delivery, cheap quality is quite good
