Part Number: TPS630250

Hi,

Please let me ask about minimum output voltage of TPS630250. I believe that it should be 2.3V, but it's 2.5V in recommended operating conditions. Actually the customer want to use with 2.3V output with 2.3A output current from Li-Ion battery (4.2V to 3.0V).

  • Hi Satoshi-san,

    As far as I know, the minimum output voltage is 2.3V for this device. I will check with out internal team why it has been listed as 2.5V in the recommended parameters, or if this is a typo.

    For this application, wouldn't a buck converter be more suitable? did you take a look at the TPS62823 ? it a new device, offering a better accuracy and efficiency for those operating conditions. As you could see online the 1k price is also lower compared to the TPS630250

    What is the end application here?
