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
DALLAS, June 29, 2020 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today 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.
Deliver ultra-fast charging in wired, wireless or on-the-go adapters
Universal charging enables portable medical devices, such as blood-pressure monitors and low-power continuous positive airway pressure (CPAP) machines, to charge from car adapters or USB-PD adapters, bringing a new level of flexibility and convenience to portable medical devices. On-the-go (OTG) charging is supported with a bi-directional operation for forward and reverse charging. For more information, read the article, "Universal and fast charging a future trend for battery charging applications."
Design smaller, more powerful applications with 50% greater power density
To learn more, read the article, "Maximize power density with buck-boost charging and USB Type-C Power Delivery."
Maximize battery run time with ultra-low power consumption
For example, video doorbell applications that typically rely on an A/C power supply can operate without interruption when the primary source of power switches to the battery pack. By helping reduce power consumption and power loss through heat dissipation, TI's chargers enable video doorbells to run longer on battery power.
