Abstract
A multi-phase (e.g., dual-phase) concurrent configuration of a power management component supports higher current levels to peripheral devices while maintaining acceptable thermal limits. A dual-phase integrated circuit (IC) having a first input/output (I/O) port coupled to a battery and a second I/O port coupled to an adapter and a peripheral device implements the configuration. The dual phase IC includes a dual-phase voltage regulator that selectively provide power (i) from the first I/O port to the second I/O port to provide power to the peripheral device or (ii) from the second I/O port to the first I/O port to provide power to the battery. A controller activates a boost phase to power the second I/O port in response to detecting a demand current of the peripheral device exceeds a maximum current available from the adapter.
