My customer has a question,
Vout(rms) is currently about 4V(rms)
The Input Level measured by Net VOUTL_OUT (C869) is about 0.38 (Vrms),
When Vout(rms) is adjusted to 5V(rms), the Vout waveform will begin to distort, please refer to waveform one and two,
The calculated output power is about 3~3.5W,
According to the LM4950 SPEC is still in the normal use specification, what causes the waveform distortion?
Please help clarify, thank you!
