Hi,

I have test TLV62095 OCP on TLV62095EVM, but I found it can drain to 3A or higher, please see below waveform.

It define OCP by switching current right? I have plot inductor current seems maximum~ 3.064A.

That I only change R1 to 20k for set Vout to 0.9V.

CH1: Vout

CH4: IL

Thanks!

Thanks for posting a waveform. Can you add Vin to it?

The 2 EVMs that I have both entered current limit at around 5A load. This is the expected behavior.

Can you also post the markings on the top of the IC?

Hi Chris,

I found I have no raise up power supply current limit, I can normal drain to ~5A load after raise up power supply current limit,

sorry for cause your inconvenience. thanks!
