  • RE: TPS562207S: Looking for a buck without that usual 'min. voltage' restriction

    Hi GGA, If you can accept Vout follows VIN, not regulated, Yes, some bucks can support, like TPS62122. As we can check that VIN UVLO of TPS62122 are VIH=0.8V, VIL=0.6V respectively. For these lower UVLO parts, the internal circuit design is much more…

  • RE: WEBENCH® Tools/TPS62177: TPS62177 Input capacitor value

    Koti, I believe the problem you are seeing is caused by the additional loading of the output capacitance during start up which is causing the input capacitor to discharge below UVLO due to your current limited voltage supply. I would not expect that simply…
