In summary, the LT3652 is a 2A, monolithic, multi-chemistry battery charger designed for use in solar power systems. These devices have the capability to charge Li-Ion/Polymer, LiFePO4, SLA battery chemistries and only draw less than 1µA from the battery during non-charging periods. The LT3652 also features a solar power supply voltage regulation loop for maximum peak power tracking in solar applications, a wide input voltage range from 4.95V to 32V, and a user-selectable charge termination option. This buck battery charger addresses high input voltage applications with solutions that require a minimum of external components.
