Problem PLIMIT

Other Parts Discussed in Thread: TPA3116D2

I'm finding instability in my circuit. By increasing the supply voltage above 17V enters saturation and cuts and back for a second.
Researching data sheet realize that the problem is in Plimit pin because in my circuit is unstable because the EVM board from Texas is stable at 7 VDC for any variation in tension.
My circuit is equal to the EVM.
Where can I have a problem ??

Hello Fernando,

Can you please mention the device you are using?, PLIMIT is a common feature name used by many parts.

Thanks and Best Regards,

Diego,

Really, I'm sorry.
I forgot to mention that I am using TPA3116D2.
I removed the capacitors C5 and C6 (1uFx16V) EVM and the defect that presents in my project, presents in EVM.
The question now is whether this value (1uFx16V) is critical? Or the capacitance may vary as much as the voltage.
I await contact.
