Vin(高直流电压)上电之后,首先通过
Vstart
脚使
Vsw
VDD
的电压逐渐上升,当
VDD
上升到 5V,内部定时器开始工作,同时电压上升,由于内部稳压管作用,电压最终到 5.6V0.65
秒之后(就是图中的 t),定时器结束,同时内部开关关断,由于电流消耗,VDD 下降,下降到 4.8V
Vsw 出现 PWM 波形,这个时候会在变压器的输出端输出一定的电压,经整流和滤波后在输出端
有输出电压 VoutVout 电压逐渐上升,当上升到设计值,系统通过光耦对 VDD 做一次很小的电
压调整,然后出现平稳,Vsw 的波形也趋向平稳。
十、应用电路
下面的电路图为常用的 5V 输出开关电源电路。在具体 PCB Layout 要注意的是,就是 C5 104
瓷片电容要尽量靠近芯片。
