Hello everybody,

My circuit supply by +15V in input. This supply is a battery (Batterie Li-Ion 4x 26F 4S1P ST1 14.8V 2.6Ah FC.) .

Actually, i reload my battery, i switch to loader but i don't use my circuit (i deconnect supply). I search component to supply my circuit and load my battery (as for notebook supply).

But i find a 5v component not 15 v component.

What propose to realize this application.

Sorry my english is awfull :(.

Fabien,

TI does not currently offer a 15V switch.

There are many DCDC converters that are compatible with a high-voltage input. These may be applicable to your load.

Regards,
Stephen

Hi Fabien,

I believe you are looking for a Li-Ion Battery Charging solution for a 4S1P configuration at 14.8V. In this case, I would urge you to consider one of our BQ24xxx Li-Ion Battery Charging ICs (example: BQ24610). They are specialized for recharging/reloading the battery in a safe way and can support 4 series cells.

If you have additional questions about which charger to use, you can post them in the battery chargers forum:
