TPS7A52: Enable to Vout Timing Specification

Hello Fraser, 

Would the EN pin be tied to VIN or is VIN already stabilized when EN is activated?

Best,

Juliette

Hello, Juliette.

VIN is already stabilised when we activate EN.

Thanks,

Fraser

Hi Fraser, 

Your start-up time will be influenced by your soft-start value capacitor. 

Would you be able to link the schematic you are using so we can verify Ton?

Bets,

Juliette

Hello, Juliette.

Please refer to the sketch below, thanks.

Hi Fraser, 

Thank you for sharing your schematic with us. I will go ahead into the lab to show you real data. Please give me a day so I can collect the data.

On the meanwhile, from simulations I obtained the following: 

The red is Ven and blue is Vout. From the point where EN is completely high to Vout completely high ~146us 

From EN high to 90% of VOUT the time shows 131us.

Thanks, Edgar.

It looks promising, since we require that it goes high in less than 100ms in our application.

Hey Fraser, 

No problem. I am currently working on this. I will update later today. 

Best, 

Edgar Acosta
