Need a PMIC with charger for LiFePO4 3.2v chemistry.

I have an application that requires a PMIC with charger for LiFePO4 3.2v chemistry. It does need to provide a boosted power path 3.3v for system electronics when running on battery and buck with running on USB.

    Hi,

    TI doesn't have a battery charger with integrated boost for system voltage but that can be easily fixed by adding a boost converter on the output.  A few of our chargers can charge down to 3.2V.  What is the desired charge current?  Is 5V USB the input voltage for the charger?  Do you want standalone or host I2C controlled charger?

    Regards,
