New buck-boost battery chargers deliver 50% greater power density and three times faster charging for USB Type-C™, USB PD and wireless dual-input charging
Texas Instruments (TI) introduced the industry’s smallest buck-boost battery charger integrated circuits, which integrate power-path management for maximum power density and universal and fast charging at up to 97% efficiency. The BQ25790 and BQ25792 support efficient charging and 10 times lower quiescent current through USB Type-C™ and USB Power Delivery (PD) ports in small personal electronics, portable medical devices and building automation applications.
The BQ25790 and BQ25792 offer the flexibility to charge batteries with one to four cells in a series and up to 5 A of charging current across the full input-voltage range (3.6 V to 24 V) for USB Type-C and USB PD applications. The chargers’ integrated dual-input selector supports multiple power sources, including wireless, USB, barrel jack and solar charging, while delivering fast charging – 97% efficiency at 30 W.
