TPS62813-Q1: PG Delay Time

Part Number: TPS62813-Q1
Other Parts Discussed in Thread: TPS62810EVM-015

Hi team,

Could you confirm the PG output delay time of TPS6281x-Q1? I found similar spec in LM636x5-Q1 datasheet but I couldn't find it in TPS6281x-Q1 datasheet.

Thanks,

Hi Muwei,

Thanks for your question.

What are you exactly referring to?

Do you mean the time between the moment when the output voltage reaches 95% and the moment when PG goes high?

Thanks,

Stefano

Hi Stefano.

Yes, please share the time between output voltage reaches 95% and PG goes high.

Hi Muwei,

I did the following measurement on TPS62810EVM-015 (VIN = 5V, VOUT = 1.8V, IOUT = 1A, removed C4).

CH1 VOUT, CH3 PG

As you can see the PG starts to raise approximately 1.5us after that VOUT reaches the 1.71V level (95%), and it takes some us to settle.

Please ask again if you have further questions.

Thanks,

Stefano
