Abstract
A multi-phase charging circuit comprises a device that can be configured for master mode operation or slave mode operation. In master mode operation, the device generates a control signal and a clock signal to control operation of a switching circuit for generating charging current. In slave mode operation, the device receives externally generated control and clock signals to control operation of its switching circuit.
