Buck-Boost Battery Chargers

Analog Devices manufactures a comprehensive line of high performance buck-boost battery chargers for any rechargeable battery chemistry, including lithium-Ion (Li-Ion), lead acid, and nickel-based. A buck-boost topology will accept input voltages above, below or equal to the battery voltage and charge the battery with high accuracy to its final charge voltage.
