Why my class D failed?
At the beginning of testing,the class D amplifier works well.But eventually,about 1 hour later,I found the current of the power supply became bigger.I power-down the device,the current still stayed at 20mA level.
I wonder whether the big current destoryed the transistors in the device,perhaps latch-up or other factors.
I have no experience in power amplifer.Please help me and I'll appreciate for your help.
