Abstract: Certain aspects of the present disclosure provide techniques and apparatus for supplying power, including battery charging. One example power supply circuit generally includes a switching regulator including an output node, a first power supply node coupled to the output node of the switching regulator, a first charge pump including a first terminal coupled to the first power supply node and including a second terminal coupled to a second power supply node, a first battery node for coupling to a first battery, and a first switch including a first terminal coupled to the first power supply node and including a second terminal connected to the first battery node.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for supplying power, including battery charging. One example power supply circuit generally includes a switching regulator including an output node; a first battery node for coupling to a first battery; a second battery node for coupling to a second battery; a first switch coupled between the output node of the switching regulator and the first battery node; and a second switch coupled between the output node of the switching regulator and the second battery node. Such a power supply circuit may independently control and monitor the charging of multiple independent batteries without using multiple chargers, may balance the batteries during discharging, and may operate without a current limit switch.
