Part Number: TPS63901
Other Parts Discussed in Thread: TPS631000, TPS631010, TPS631011

Tool/software:

I will be using these two batteries for my product.

1) LiFePO4 - 2V to 3.65V

2) Li-Polymer - 3V to 4.2V

Can TPS63901 deliver an output current of 1.1A for these two batteries for a 3.3V output voltage?

Figure 8-2 in datasheet shows the output current capability versus input voltage, you can check it.

@Tao Zhang, If this is true, this regulator will not work for either of my batteries, correct?

Hi ,

I am afraid so, recomment TPS631000/TPS631010/TPS631011 for your application.

I have chosen TPS63802DLAR, which can work with both the batteries above. I have sent schematics to your personal message.
