my design is
:input 3.3V,
:EN connect to VIN through 10kohm resistor,
:input and out capacitor is 1uF,NR capacitor is 10nF
with no load output is 2.2V
Has this been damaged? or other reasons?
Other Parts Discussed in Thread: LM5176 您好!我们按照WEBENCH参考设计,用LM5176实现输入9-36V,输出15V的Buck-Boost电源电路,原理图见附件。
现在调试时发现,输入电压大于等于17V时输出才能稳定输出,9-17V范围输出一直振荡,输出波形见附件。
请帮忙分析一下问题原因,谢谢!
