Abstract: The present embodiments relate generally to managing power in a system including a battery, and more particularly to a flexible or hybrid battery charging topology for a system including a battery. In addition to being capable of operating in a conventional narrow voltage DC (NVDC) buck-boost charger mode, it is also capable of operating in a new “turbo power buck-boost” mode, where the input voltage is directly fed to the system load, bypassing the inductor. Compared with the conventional NVDC buck-boost charger topology, the flexible or hybrid topology provided by the present embodiments reduces the inductor size otherwise needed to support new mobile charging protocols, among many other benefits and advantages.
