USB BOOST CHARGER FOR 2S LI-ION/PO

Hi,

our customer is looking for a USB to 2S Li-Ion/Po battery charger. As the USB voltage is 5V the voltage should be boosted to around 9V-10V in order to provide a charging voltage to the batteries. There are low cost boosts and switch mode buck charges (not cost effective) but the customers is looking for a boost solution. Anything available?

(Charge current is neglected at this time, I just need to understand if TI supports or will support this solution)

Thanks,

Ran
