TPS63070: Vin=2V~12V Iout=1A Vout=3.3V

Part Number: TPS63070

Hi Sir,

As title, Does TPS63070 can support Vin=2V~12V Iout=1A Vout=3.3V condition?

Datasheet shows can support 2A output current but need in Vin =4V condition?

And I also using webench tool seems show hit first level OCP.

Thanks!

Jeff

    Hi Jeff,

    here is a special feature with TPS63070. 

    before the output voltage is below the PG threshold, the input current limit will reduce to 1A. that is what happened in you Webench

    additional, the start-up voltage should higher than 3V for TPS63070.

    so i am afraid this device can not supoort your case.

    Regards
