MAX17005 Overview
These circuits feature a new high-frequency current-mode architecture that significantly reduces ponent size and cost . The charger uses a high-side MOSFET with n-channel synchronous rectifier. Widely adjustable charge current, charge voltage, and input current limit simplify the construction of highly accurate and efficient chargers.
