Abstract
Embodiments described herein provides a battery charging circuit that boosts an input current and feeds the boosted input current to a battery for fast charging. Specifically, the battery charging circuit includes a low dropout regulator (LDO) for providing a voltage, a switch mode charger, coupled between the LDO and a battery, and a capacitor divider, coupled between the LDO and the battery, in parallel to the switch mode charger, for dividing the voltage outputted from the LDO by a factor.
