Li-Ion Battery Reference Design (42V @ 2A)

Hi Bob,

The TI charger team currently does not have a single IC solution for this type of application.  After doing a search at www.ti.com/reference-designs, I found the following which might work for you.

If the input voltage never drops below the 36V final charge voltage, then a buck-boost converter might be overkill. 

Regards,

Jeff
